CATH Clusters

Superfamily HybD-like
Functional Family Hydrogenase 3 maturation endopeptidase HyCI

Enzyme Information

3.4.23.51
HycI peptidase.
based on mapping to UniProt P0AEV9
This enzyme specifically removes a 32-amino acid peptide from the C-terminus of the precursor of the large subunit of E.coli hydrogenase 3 by cleavage at the C-terminal side of Arg-537.
-!- 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. -!- Belongs to peptidase family A31.
