EC 2.6.1.21     
Accepted name: D-amino-acid transaminase
Reaction: D-alanine + 2-oxoglutarate = pyruvate + D-glutamate
Other name(s): D-aspartate transaminase; D-alanine aminotransferase; D-aspartic aminotransferase; D-alanine-D-glutamate transaminase; D-alanine transaminase; D-amino acid aminotransferase
Systematic name: D-alanine:2-oxoglutarate aminotransferase
Comments: A pyridoxal-phosphate protein. The enzyme from thermophilic Bacillus species acts on many D-amino acids with D-alanine and D-2-aminobutyrate as the best amino donors. It can similarly use any of several 2-oxo acids as amino acceptor, with 2-oxoglutarate and 2-oxobutyrate among the best. The enzyme from some other sources has a broader specificity [6].
