General annotation (Comments)

Function

Catalyzes the deacylation of 7 beta-(4-carboxybutanamido)cephalosporanic acid (glutaryl-7-aminocephalosporanic acid or GL-7-ACA) to 7-aminocephalosporanic acid (7-ACA). Ref.2

Catalytic activity

(7R)-7-(4-carboxybutanamido)cephalosporanate + H2O = (7R)-7-aminocephalosporanate + glutarate.

Subunit structure

Heterotetramer of two alpha and two beta subunits processed from the same precursor. Ref.3

Subcellular location

Periplasm Ref.2.

Induction

By glutaric acid. Ref.2

Sequence similarities

Belongs to the peptidase S45 family.
