General annotation (Comments)

Function

Catalyzes the hydrolysis of reduced and non-reduced folates to pteroates and L-glutamate. This enzyme has a broad specificity.

Catalytic activity

Release of C-terminal glutamate residues from a wide range of N-acylating moieties, including peptidyl, aminoacyl, benzoyl, benzyloxycarbonyl, folyl and pteroyl groups.

Cofactor

Binds 2 zinc ions per subunit. Ref.4

Subunit structure

Homodimer.

Pharmaceutical use

Used clinically as a folate-depleting, antitumor agent.

Sequence similarities

Belongs to the peptidase M20A family.
