3.4.23.B20 precursor of the large subunit of hydrogenase 2 + H2O Escherichia coli the final step of maturation of [NiFe]-hydrogenases involves the activity of an endopeptidase which removes an oligopeptide from the C-terminus of the large subunit of hydrogenase 2 (UniProt: P0ACE0). The proteolytic maturation is followed by a conformational change, closing of the metal centre, its assembly with the small hydrogenase subunit and finally in the appearance of enzyme activity ?
