hypothetical protein HMPREF9730_01981 [Treponema denticola AL-2]

Protein Classification

sulfurtransferase TusA family protein; cysteine desulfurase/sulfurtransferase TusA family protein( domain architecture ID 10130710)

sulfurtransferase TusA family protein similar to sulfurtransferase TusA, which interacts with cysteine desulfurase IscS and acts as the first member in a sulfur relay mechanism, transfering sulfur to the TusBCD complex| cysteine desulfurase/sulfurtransferase TusA family protein contains an N-terminal pyridoxal-5'-phoshate dependent enzyme that catalyzes the removal of elemental sulfur atoms from cysteine to produce alanine, and a C-terminal TusA domain that may interact with cysteine desulfurase and acts as the first member in a sulfur relay mechanism

SirA_like_N, a protein of unknown function with an N-terminal SirA-like domain. The SirA, YedF, YeeD protein family is present in bacteria as well as archaea. SirA (also known as UvrY, and YhhP) belongs to a family of a two-component response regulators that controls secondary metabolism and virulence. The other member of this two-component system is a sensor kinase called BarA which phosphorylates SirA. A variety of microorganisms have similar proteins, all of which contain a common CPxP sequence motif in the N-terminal region. YhhP is suggested to be important for normal cell division and growth in rich nutrient medium. Moreover, despite a low primary sequence similarity, the YccP structure closely resembles the non-homologous C-terminal RNA-binding domain of E. coli translation initiation factor IF3. The signature CPxP motif serves to stabilize the N-terminal helix as part of the N-capping box and might be important in mRNA-binding.

 6-65 4.24e-15

selenium metabolism protein YedF; Members of this protein family are about 200 amino acids in size, and include the uncharacterized YedF protein of Escherichia coli. This family shares an N-terminal domain, modeled by pfam01206, with the sulfurtransferase TusA (also called SirA). The C-terminal domain includes a typical redox-active disulfide motif, CGXC. This protein family found only among those genomes that also carry the selenium donor protein SelD, and its connection to selenium metabolism is indicated by the method of partial phylogenetic profiling vs. SelD. Its gene typically is found next to selD. Members of this family are found even when selenocysteine and selenouridine biosynthesis pathways are, except for SelD, completely absent, as in Enterococcus faecalis. Its role in selenium metabolism is unclear, but may include either detoxification or a role in labile selenoprotein biosynthesis.
