The DNA sequence contains a fourth open reading frame, designated frhD (476 bp), encoding a polypeptide (delta) that does not copurify with the active enzyme. Expression of the frh gene cluster in Escherichia coli shows that four polypeptides are synthesized. When analyzed by SDS-PAGE, the proteins migrate with mobilities consistent with their calculated molecular weights. In order to understand the mechanism of H2 oxidation by this enzyme, localization of redox cofactors (Ni, Fe/S, FAD) to specific subunits and information on their structure is needed. This has been hindered due to the refractory nature of the enzyme to denaturation methods needed in order to obtain individual subunits with cofactors intact. In this paper we discuss the possible localization of the redox cofactors as implicated from the DNA-derived protein sequences of the subunits. The amino acid sequences of the subunits of the FRH are compared with those of other Ni-containing hydrogenases, including the methyl viologen reducing hydrogenase (MVH) of M. thermoautotrophicum delta H."xsd:string |
