25-231 1.59e-73

fungal YRO2 and related proteins, member of the seven-transmembrane GPCR superfamily; This subgroup includes the yeast YRO2 protein and it closely related proteins. Although the exact function of these proteins is unknown, they show strong sequence homology to the family of microbial rhodopsins, also known as type I rhodopsins, comprising the light-driven inward chloride pump halorhodopsin (HR), the outward proton pump bacteriorhodopsin (BR), the light-gated cation channel channelrhodopsin (ChR), the light-sensor activating transmembrane transducer protein sensory rhodopsin II (SRII), and the other light-driven proton pumps such as blue-light absorbing and green-light absorbing proteorhodopsins, among others. Microbial rhodopsins have been found in various single-celled microorganisms from all three domains of life, including halophile archaea, gamma-proteobacteria, cyanobacteria, fungi, and green algae. While microbial (type 1) and animal (type 2) rhodopsins have no sequence similarity with each other, they share a common architecture consisting of seven-transmembrane alpha-helices (TM) connected by extracellular loops and intracellular loops. Both types of rhodopsins consist of opsin and a covalently attached retinal (the aldehyde of vitamin A), a photoreactive chromophore, via a protonated Schiff base linkage to an amino group of lysine in the middle of the seventh transmembrane helix (TM7). Upon the absorption of light, microbial rhodopsins undergo light-induced photoisomerization of all-trans retinal into the 13-cis isomer, whereas the photoisomerization of 11-cis retinal to all-trans isomer occurs in the animal rhodopsins. While animal visual rhodopsins are activated by light to catalyze GDP/GTP exchange in the alpha subunit of the retinal G protein transducin (Gt), microbial rhodopsins do not activate G proteins, but instead can function as light-dependent ion pumps, cation channels, and sensors.

They are integral membrane proteins believed to contain seven transmembrane (TM) domains, the last of which contains the attachment point for retinal (a conserved lysine). This family also includes distantly related proteins that do not contain the retinal binding lysine and so cannot function as opsins. Some fungal examples are: Swiss:O74870, Swiss:P25619, Swiss:P38079, Swiss:Q12117.

Both types of rhodopsins consist of opsin and a covalently attached retinal (the aldehyde of vitamin A), a photoreactive chromophore, via a protonated Schiff base linkage to an amino group of lysine in the middle of the seventh transmembrane helix (TM7). Upon the absorption of light, microbial rhodopsins undergo light-induced photoisomerization of all-trans retinal into the 13-cis isomer, whereas the photoisomerization of 11-cis retinal to all-trans isomer occurs in the animal rhodopsins. While animal visual rhodopsins are activated by light to catalyze GDP/GTP exchange in the alpha subunit of the retinal G protein transducin (Gt), microbial rhodopsins do not activate G proteins, but instead can function as light-dependent ion pumps, cation channels, and sensors.

type 1 opsins, member of the seven-transmembrane GPCR superfamily; This group represents the microbial rhodopsin family, also known as type 1 rhodopsins, which can function as light-dependent ion pumps, cation channels, and sensors. They have been found in various single-celled microorganisms from all three domains of life, including halophile archaea, gamma-proteobacteria, cyanobacteria, fungi, and green algae. Members of the type I rhodopsin family include: light-driven inward chloride pump halorhodopsin (HR); light-driven outward proton pump bacteriorhodopsin (BR); light-gated cation channel channelrhodopsin (ChR); light-sensor activating transmembrane transducer proteins, sensory rhodopsin I and II (SRI and II); light-sensor activating soluble transducer protein Anabaena sensory rhodopsin (ASR); and other light-driven proton pumps such as blue-light-absorbing and green-light absorbing proteorhodopsins, among others.

29-231 7.44e-13

light-driven outward proton pump bacteriorhodopsin, member of the seven-transmembrane GPCR superfamily; Bacteriorhodopsin (BR) serves as a light-driven retinal-binding outward proton pump, generating an outside positive membrane potential and thus creating an inwardly directed proton motive force (PMF) necessary for ATP synthesis. BR belongs to the microbial rhodopsin family, also known as type I rhodopsins, comprising light-driven inward chloride pump halorhodopsin (HR), light-gated cation channel channelrhodopsin (ChR), light-sensor activating transmembrane transducer protein sensory rhodopsin II (SRII), light-sensor activating soluble transducer protein Anabaena sensory rhodopsin (ASR), and other light-driven proton pumps such as blue-light absorbing and green-light absorbing proteorhodopsins, among others. They have been found in various single-celled microorganisms from all three domains of life, including halophile archaea, gamma-proteobacteria, cyanobacteria, fungi, and green algae.

25-231 6.95e-10

Anabaena sensory rhodopsin and similar proteins, member of the seven-transmembrane GPCR superfamily; This subgroup includes eubacterial sensory rhodopsin from the freshwater cyanobacterium Anabaena and its closely related proteins. Unlike other sensory rhodopsins (SRI and SRII), the Anabaena sensory rhodopsin (ASR) activates a soluble transducer protein (ASRT), which may leading to transcriptional control of several genes. Although ASRT was shown to interact with DNA in vitro, the exact mechanism of photosensory transduction is not clearly understood. Moreover, the regulation of CRP (cAMP receptor protein) expression by ASR has been reported demonstrating a direct interaction of the C-terminal region of ASR with DNA, suggesting that ASR itself may also work as a transcription factor. ASR belongs to the microbial rhodopsin family, also known as type I rhodopsins, comprising the light-driven inward chloride pump halorhodopsin (HR), the outward proton pump bacteriorhodopsin (BR), the light-gated cation channel channelrhodopsin (ChR), the light-sensor activating transmembrane transducer protein sensory rhodopsin II (SRII), and the other light-driven proton pumps such as blue-light absorbing and green-light absorbing proteorhodopsins, among others.

light-sensor activating transmembrane transducer protein sensory rhodopsin I and II; member of the seven-transmembrane GPCR superfamily; This subgroup includes the light-sensor activating transmembrane transducer proteins, sensory rhodopsin I (SRI) and II (SRII, also called phoborhodopsin). SRI and SRII are responsible for positive (attractive) and negative (repellent) phototaxis in halobacteria, respectively, thereby controlling the cell's directional movement in response to changes in light intensity by swimming either towards or away from the light. Both sensory rhodopsins belong to the family of microbial rhodopsins, also known as type I rhodopsins, consisting of the light-driven inward chloride pump halorhodopsin (HR), the outward proton pump bacteriorhodopsin (BR), the light-gated cation channel channelrhodopsin (ChR), and the other light-driven proton pumps such as blue-light absorbing and green-light absorbing proteorhodopsins, among others.

Bacteriorhodopsin-like protein; The bacterial opsins are retinal-binding proteins that provide light- dependent ion transport and sensory functions to a family of halophilic bacteria. They are integral membrane proteins believed to contain seven transmembrane (TM) domains, the last of which contains the attachment point for retinal (a conserved lysine). This family also includes distantly related proteins that do not contain the retinal binding lysine and so cannot function as opsins. Some fungal examples are: Swiss:O74870, Swiss:P25619, Swiss:P38079, Swiss:Q12117.

102-231 6.41e-05

light-driven inward chloride pump halorhodopsin, member of the seven-transmembrane GPCR superfamily; Halorhodopsin (HR) acts as a light-driven inward-directed chloride pump. When activated by yellow light, HR pumps chloride ions into the cell cytoplasm, generating a negative-inside membrane potential which drives proton uptake. The resulting electrochemical ion gradient provides an energy source to the cell and contributes to pH homeostasis. HR is found in phylogenetically ancient archaea, known as halobacteria which live in high salty environments. HR belongs to the microbial rhodopsin family, also known as type I rhodopsins, comprising light-driven retinal-binding outward pump bacteriorhodopsin (BR), light-gated cation channel channelrhodopsin (ChR), light-sensor activating transmembrane transducer protein sensory rhodopsin II (SRII), light-sensor activating soluble transducer protein Anabaena sensory rhodopsin (ASR), and other light-driven proton pumps such as blue-light absorbing and green-light absorbing proteorhodopsins, among others. They have been found in various single-celled microorganisms from all three domains of life, including halophile archaea, gamma-proteobacteria, cyanobacteria, fungi, and green algae. While microbial (type 1) and animal (type 2) rhodopsins have no sequence similarity with each other, they share a common architecture consisting of seven-transmembrane alpha-helices (TM) connected by extracellular loops and intracellular loops. Both types of rhodopsins consist of opsin and a covalently attached retinal (the aldehyde of vitamin A), a photoreactive chromophore, via a protonated Schiff base linkage to an amino group of lysine in the middle of the seventh transmembrane helix (TM7). Upon the absorption of light, microbial rhodopsins undergo light-induced photoisomerization of all-trans retinal into the 13-cis isomer, whereas the photoisomerization of 11-cis retinal to all-trans isomer occurs in the animal rhodopsins. While animal visual rhodopsins are activated by light to catalyze GDP/GTP exchange in the alpha subunit of the retinal G protein transducin (Gt), microbial rhodopsins do not activate G proteins, but instead can function as light-dependent ion pumps, cation channels, and sensors.
