Motif

Feature keyPosition(s)LengthDescriptionGraphical viewFeature identifierActions
Motifi97 – 1048Cysteine switch By similarity

Domaini

The conserved cysteine present in the cysteine-switch motif binds the catalytic zinc ion, thus inhibiting the enzyme. The dissociation of the cysteine from the zinc ion upon the activation-peptide release activates the enzyme.

Sequence similaritiesi

Belongs to the peptidase M10A family.
Contains 4 hemopexin repeats.

Keywords - Domaini

Repeat, Signal
