EC 3.4.23.51

Names

Accepted name:
HycI peptidase
Other names:
HycI
HycE processing protein
Systematic name:
-

Reaction

Comments:

The reaction requires nickel to be bound to the precursor of the large subunit of hydrogenase 3. The endopeptidase uses the metal in the large subunit of [NiFe]-hydrogenases as a recognition motif [1]. In peptidase family A31.
