6-153 4.96e-63

Endopeptidases belonging to membrane-bound hydrogenases group. These hydrogenases transfer electrons from H2 to a cytochrome that is bound to a membrane-located complex coupling electron transfer to transmembrane proton translocation. Endopeptidase HybD from E. coli is well studied in this group. Maturation of [NiFe] hydrogenases include proteolytic processing of large subunit, assembly with other subunits, and formation of the nickel metallocenter. Hydrogenase maturation endopeptidase (HybD) cleaves a short C-terminal peptide after a His or an Arg residue in the large subunit (pre-HybC) of hydrogenase 2 (hyb operon) in E. coli. This cleavage is nickel dependent. A variety of endopeptidases belong to this group that are similar in function and sequence homology. They include such proteins as HynC, HoxM, and HupD.

7-149 1.59e-44

Hydrogenase specific C-terminal endopeptidases, also called Hydrogen Maturation Proteases (H2MP). These enzymes belong to the peptidase family M52. Maturation of [FeNi] hydrogenases includes formation of the nickel metallocenter, proteolytic processing and assembly with other subunits. Hydrogenase maturation endopeptidases are responsible for the proteolytic processing, liberating a short C-terminal peptide by cleaving after a His or an Arg residue, e.g., HycI (E. coli) is involved in processing of HypE, the large subunit of hydrogenase 3. This cleavage is nickel dependent. This CD also includes such hydrogenase-processing proteins as HydD, HupW, and HoxW, as well as, proteins of the F420-reducing hydrogenase of methanogens (e.g., FrcD). Also included, is the Pyrococcus furiosus FrxA protein, a bifunctional endopeptidase/ sulfhydrogenase found in NADP-reducing hyperthermophiles.The Pyrococcus FrxA is not related to those found in Helicobacter pylori.

7-124 2.47e-18

Endopeptidases belonging to F420-reducing hydrogenases group. These hydrogenases from methanogens are encoded by the fru, frc, or frh genes. Sequence comparison indicates that fruD and frcD gene products from Methanococcus voltae are similar to HycI protease of Escherichia coli and are putatively involved in the C-terminal processing of large subunits (FruA and FrcA respectively). FrhD (F420 reducing hydrogenase delta subunit) enzyme belongs to the gene cluster of 8-hydroxy-5-deazaflavin (F420) reducing hydrogenase (FRH) from the thermophilic methanogen Methanobacterium thermoautotrophicum delta H. FrhD subunit is putatively involved in the processing of the coenzyme F420 hydrogenase-processing. It is similar to those frhD genes found in Methanomicrobia and Methanobacteria. It is different from the FrhD conserved domain found in methyl viologen-reducing hydrogenase and F420-non-reducing hydrogenase iron-sulfur subunit D.

7-132 7.67e-14

Endopeptidases belonging to membrane-bound hydrogen evolving hydrogenase group. In hydrogenase 3 from E coli, the maturation of the large subunit (HycE) requires the cleavage of a C-terminal peptide by the endopeptidase HycI, before the final formation of the [NiFe] metallocenter. HycI protease is a monomer and lacks characteristic signature motifs of serine, zinc, cysteine, or acid proteases and thus its cleavage reaction is not inhibited by conventional inhibitors of serine and metalloproteases. Such hydrogenases as those from Methanosarcina barkeri (EchCE) and Rhodospirillum rubrum (CooLH) also belong to this group of membrane-bound hydrogen evolving hydrogenase. Sequence comparison of the large subunits from related hydrogenase indicates that in contrast to EchE (358 amino acids) and CooH (361 amino acids), the large subunit HycE (569 amino acids) contains an extra carboxy-terminal stretch of 32 amino acids that is cleaved during the maturation process. In the absence of this C-terminal stretch, there is no homolog of endopeptidase HycI found in these two related hydrogenase.

6-149 1.73e-11

This group of endopeptidases include HupW enzymes that are specific to the cyanobacterial hydrogenase and are involved in the C-terminal cleavage of the hydrogenase large subunit precursor protein. Cyanobacterial nickel-iron (NiFe)-hydrogenases are found exclusively in the N2-fixing strains and are encoded by hup (hydrogen uptake) genes. These uptake hydrogenases are heterodimers with a large (hupL) and small subunit (hupS) and catalyze the consumption of the H2 produced during N2 fixation. Sequence similarity shows that the putative metal-binding resides are well conserved in this group of hydrogen maturation proteases. This group also includes such proteins as the hydrogenase III from Aquifex aeolicus.

Endopeptidases that belong to the bidirectional NAD-linked hydrogenase group.

These bidirectional hydrogenases are heteropentamers encoded by the hox (hydrogen oxidation) genes, in which complex HoxEFU shows the diaphorase activity, and HoxYH constitutes the NiFe-hydrogenase.
