Protein attributes

Sequence length	558 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Besides the cephalosporin acylase I activity which converts GL-7ACA into 7-ACA; this enzyme displays some gamma glutamyltranspeptidase activity.
Catalytic activity	7-beta-(4-carboxybutanamido)-cephalosporanic acid + H2O = 7-aminocephalosporanic acid + glutaric acid. (5-L-glutamyl)-peptide + an amino acid = peptide + 5-L-glutamyl amino acid.
Subunit structure	Dimer of two non-identical chains processed from the same precursor.
Sequence similarities	Belongs to the gamma-glutamyltransferase family.
