SYSTEMATIC NAME
IUBMB Comments
cephalosporin-C:2-oxoglutarate aminotransferase
A number of D-amino acids, including D-alanine, D-aspartate and D-methionine can also act as amino-group donors. Although this enzyme acts on several free D-amino acids, it differs from EC 2.6.1.21, D-alanine transaminase, in that it can use cephalosporin C as an amino donor.
