KEGG   ENZYME: 2.6.1.74
Entry
EC 2.6.1.74                 Enzyme                                 
Name
cephalosporin-C transaminase;
cephalosporin C aminotransferase;
L-alanine:cephalosporin-C aminotransferase
Class
Transferases;
Transferring nitrogenous groups;
Transaminases
Sysname
cephalosporin-C:2-oxoglutarate aminotransferase
Reaction(IUBMB)
(7R)-7-(5-carboxy-5-oxopentanoyl)aminocephalosporinate + D-glutamate = cephalosporin C + 2-oxoglutarate [RN:R03063]
Reaction(KEGG)
R03063
Substrate
(7R)-7-(5-carboxy-5-oxopentanoyl)aminocephalosporinate [CPD:C04712];
D-glutamate [CPD:C00217]
Product
cephalosporin C [CPD:C00916];
2-oxoglutarate [CPD:C00026]
Comment
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.
