Glossary: cephalosporin C = (7R)-7-(5-carboxy-5-oxopentanamido)cephalosporanate
Other name(s): cephalosporin C aminotransferase; L-alanine:cephalosporin-C aminotransferase
Systematic name: cephalosporin-C:2-oxoglutarate aminotransferase
Comments: 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 22.214.171.124, D-alanine transaminase, in that it can use cephalosporin C as an amino donor.
