Function
function
Multifunctional aminotransferase with a broad substrate specifcity. Catalyzes the conversion of glyoxylate to glycine using alanine as the amino donor. Catalyzes metabolism of not L- but the D-isomer of D-beta-aminoisobutyric acid to generate 2-methyl-3-oxopropanoate and alanine. Catalyzes the transfer of the amino group from beta-alanine to pyruvate to yield L-alanine and 3-oxopropanoate. Can metabolize NG-monomethyl-L-arginine (NMMA), asymmetric NG,NG-dimethyl-L-arginine (ADMA) and symmetric NG,N'G-dimethyl-L-arginine (SDMA). ADMA is a potent inhibitor of nitric-oxide (NO) synthase, and this activity provides mechanism through which the kidney regulates blood pressure.
Catalytic activity
- (2S)-2-aminobutanoate + glyoxylate = 2-oxobutanoate + glycine
- N(omega),N(omega)-dimethyl-L-arginine + 2-oxobutanoate = 5-(3,3-dimethylguanidino)-2-oxopentanoate + (2S)-2-aminobutanoate
- 2-oxohexanoate + N(omega),N(omega)-dimethyl-L-arginine = L-2-aminohexanoate + 5-(3,3-dimethylguanidino)-2-oxopentanoate
- 2-oxopentanoate + N(omega),N(omega)-dimethyl-L-arginine = 5-(3,3-dimethylguanidino)-2-oxopentanoate + L-2-aminopentanoate
- oxaloacetate + L-alanine = L-aspartate + pyruvate
- L-ornithine + pyruvate = 5-amino-2-oxopentanoate + L-alanine
- N(omega),N('omega)-dimethyl-L-arginine + pyruvate = 5-(3,3'-dimethylguanidino)-2-oxopentanoate + L-alanine
- N(omega),N(omega)-dimethyl-L-arginine + oxaloacetate = 5-(3,3-dimethylguanidino)-2-oxopentanoate + L-aspartate
- N(omega),N(omega)-dimethyl-L-arginine + pyruvate = 5-(3,3-dimethylguanidino)-2-oxopentanoate + L-alanine
- N(omega)-methyl-L-arginine + pyruvate = 5-(3-methylguanidino)-2-oxopentanoate + L-alanine
- L-ornithine + glyoxylate = 5-amino-2-oxopentanoate + glycine
- N(omega),N('omega)-dimethyl-L-arginine + glyoxylate = 5-(3,3'-dimethylguanidino)-2-oxopentanoate + glycine
- N(omega),N(omega)-dimethyl-L-arginine + glyoxylate = 5-(3,3-dimethylguanidino)-2-oxopentanoate + glycine
- N(omega)-methyl-L-arginine + glyoxylate = 5-(3-methylguanidino)-2-oxopentanoate + glycine
