Peptidase M1 family similar to aminopeptidase N catalytic domain; This family contains bacterial M1 peptidases with smilarity to the catalytic domain of aminopeptidase N (APN; CD13; alanyl aminopeptidase; EC 3.4.11.2), a type II integral membrane protease belonging to the M1 gluzincin family. APN preferentially cleaves neutral amino acids from the N-terminus of oligopeptides and, in higher eukaryotes, is present in a variety of human tissues and cell types (leukocyte, fibroblast, endothelial and epithelial cells). APN expression is dysregulated in inflammatory diseases such as chronic pain, rheumatoid arthritis, multiple sclerosis, systemic sclerosis, systemic lupus erythematosus, polymyositis/dermatomyosytis and pulmonary sarcoidosis, and is enhanced in tumor cells such as melanoma, renal, prostate, pancreas, colon, gastric and thyroid cancers. It is predominantly expressed on stem cells and on cells of the granulocytic and monocytic lineages at distinct stages of differentiation, thus considered a marker of differentiation. Thus, APN inhibition may lead to the development of anti-cancer and anti-inflammatory drugs. APNs are also present in many pathogenic bacteria and represent potential drug targets. Some APNs have been used commercially, such as one from Lactococcus lactis used in the food industry. APN also serves as a receptor for coronaviruses, although the virus receptor interaction site seems to be distinct from the enzymatic site and aminopeptidase activity is not necessary for viral infection. APNs have also been extensively studied as putative Cry toxin receptors. Cry1 proteins are pore-forming toxins that bind to the midgut epithelial cell membrane of susceptible insect larvae, causing extensive damage. Several different toxins, including Cry1Aa, Cry1Ab, Cry1Ac, Cry1Ba, Cry1Ca and Cry1Fa, have been shown to bind to APNs; however, a direct role of APN in cytotoxicity has been yet to be firmly established.

65-570 2.06e-15

Peptidase M1 family similar to aminopeptidase N catalytic domain; This family contains mostly bacterial and some archaeal M1 peptidases with smilarity to the catalytic domain of aminopeptidase N (APN; CD13; alanyl aminopeptidase; EC 3.4.11.2), a type II integral membrane protease belonging to the M1 gluzincin family. APN preferentially cleaves neutral amino acids from the N-terminus of oligopeptides and, in higher eukaryotes, is present in a variety of human tissues and cell types (leukocyte, fibroblast, endothelial and epithelial cells). APN expression is dysregulated in inflammatory diseases such as chronic pain, rheumatoid arthritis, multiple sclerosis, systemic sclerosis, systemic lupus erythematosus, polymyositis/dermatomyosytis and pulmonary sarcoidosis, and is enhanced in tumor cells such as melanoma, renal, prostate, pancreas, colon, gastric and thyroid cancers. It is predominantly expressed on stem cells and on cells of the granulocytic and monocytic lineages at distinct stages of differentiation, thus considered a marker of differentiation. Thus, APN inhibition may lead to the development of anti-cancer and anti-inflammatory drugs. APNs are also present in many pathogenic bacteria and represent potential drug targets. Some APNs have been used commercially, such as one from Lactococcus lactis used in the food industry. APN also serves as a receptor for coronaviruses, although the virus receptor interaction site seems to be distinct from the enzymatic site and aminopeptidase activity is not necessary for viral infection. APNs have also been extensively studied as putative Cry toxin receptors. Cry1 proteins are pore-forming toxins that bind to the midgut epithelial cell membrane of susceptible insect larvae, causing extensive damage. Several different toxins, including Cry1Aa, Cry1Ab, Cry1Ac, Cry1Ba, Cry1Ca and Cry1Fa, have been shown to bind to APNs; however, a direct role of APN in cytotoxicity has been yet to be firmly established.

379-555 9.43e-13

Peptidase M1 family includes the catalytic domains of aminopeptidase N and leukotriene A4 hydrolase; The model represents the catalytic domains of M1 peptidase family members including aminopeptidase N (APN) and leukotriene A4 hydrolase (LTA4H). All peptidases in this family bind a single catalytic zinc ion which is tetrahedrally co-ordinated by three amino acid ligands and a water molecule that forms the nucleophile upon activation during catalysis. APN preferentially cleaves neutral amino acids from the N-terminus of oligopeptides and is present in a variety of human tissues and cell types. APN expression is dysregulated in many inflammatory diseases and is enhanced in numerous tumor cells, making it a lead target in the development of anti-cancer and anti-inflammatory drugs. LTA4H is a bifunctional enzyme, possessing an aminopeptidase as well as an epoxide hydrolase activity. The two activities occupy different, but overlapping sites. The activity and physiological relevance of the aminopeptidase in LTA4H is as yet unknown, while the epoxide hydrolase converts leukotriene A4 (LTA4) into leukotriene B4 (LTB4), a potent chemotaxin that is fundamental to the inflammatory response of mammals.

Peptidase M1 family, including aminopeptidase N catalytic domain; This model represents the catalytic domain of aminopeptidase N (APN; CD13; alanyl aminopeptidase; EC 3.4.11.2), a type II integral membrane protease belonging to the M1 gluzincin family. It includes bacterial-type alanyl aminopeptidases as well as PfA-M1 aminopeptidase (Plasmodium falciparum-type). APN preferentially cleaves neutral amino acids from the N-terminus of oligopeptides and, in higher eukaryotes, is present in a variety of human tissues and cell types (leukocyte, fibroblast, endothelial and epithelial cells). APN expression is dysregulated in inflammatory diseases such as chronic pain, rheumatoid arthritis, multiple sclerosis, systemic sclerosis, systemic lupus erythematosus, polymyositis/dermatomyosytis and pulmonary sarcoidosis, and is enhanced in tumor cells such as melanoma, renal, prostate, pancreas, colon, gastric and thyroid cancers. It is predominantly expressed on stem cells and on cells of the granulocytic and monocytic lineages at distinct stages of differentiation, thus considered a marker of differentiation. Thus, APN inhibition may lead to the development of anti-cancer and anti-inflammatory drugs. APNs are also present in many pathogenic bacteria and represent potential drug targets. Some APNs have been used commercially, such as one from Lactococcus lactis used in the food industry. APN also serves as a receptor for coronaviruses, although the virus receptor interaction site seems to be distinct from the enzymatic site and aminopeptidase activity is not necessary for viral infection. APNs have also been extensively studied as putative Cry toxin receptors. Cry1 proteins are pore-forming toxins that bind to the midgut epithelial cell membrane of susceptible insect larvae, causing extensive damage. Several different toxins, including Cry1Aa, Cry1Ab, Cry1Ac, Cry1Ba, Cry1Ca and Cry1Fa, have been shown to bind to APNs; however, a direct role of APN in cytotoxicity has been yet to be firmly established.
