Description

This group of sequence are classed as unassigned endopeptidases belonging to the MEROPS peptidase family A31 (HybD endopeptidase family, clan AE). The sequences in this family represent the delta subunit, FrhD, of the nickel-containing 8-hydroxy-5-deazaflavin reducing hydrogenase, otherwise known as coenzyme F420-reducing hydrogenase. The delta subunit is not part of the active FRH heterotrimer, but is probably a protease required for maturation. The alpha subunit contains the metallo centre, which binds nickel. When nickel binds to the metallo centre the alpha subunit is processed to the active enzyme by cleavage at a conserved site near the C terminus. The delta subunit is thought to be responsible for these cleavages [PMID: 2207102].
