Multifunctional aminotransferase with a broad substrate specificity (PubMed:20018850, PubMed:23023372, PubMed:24586340). Catalyzes the conversion of glyoxylate to glycine using alanine as the amino donor (By similarity). Catalyzes metabolism of not L- but the D- isomer of D-beta-aminoisobutyric acid to generate 2-methyl-3- oxopropanoate and alanine (PubMed:24586340). Catalyzes the transfer of the amino group from beta-alanine to pyruvate to yield L-alanine and 3- oxopropanoate (By similarity). Can metabolize NG-monomethyl-L-arginine (NMMA), asymmetric NG,NG-dimethyl-L-arginine (ADMA) and symmetric NG,N'G-dimethyl-L-arginine (SDMA) (PubMed:20018850, PubMed:23023372). ADMA is a potent inhibitor of nitric-oxide (NO) synthase, and this activity provides mechanism through which the kidney regulates blood pressure (PubMed:20018850, PubMed:23023372). {ECO:0000250|UniProtKB:Q64565, ECO:0000269|PubMed:20018850, ECO:0000269|PubMed:23023372, ECO:0000269|PubMed:24586340}. This is the function of Ensembl gene identifier ENSG00000113492 (AGXT2, alanine--glyoxylate aminotransferase 2).
