Intimate relationships of the large and the small subunits of all nickel hydrogenases with two nuclear-encoded subunits of mitochondrial NADH: ubiquinone oxidoreductase

Abstract

The sequence pattern CxxCxnGxCxxxGxmGCPP, thus far found in the small subunits from 21 different nickel hydrogenases, appears also to be present in the PSST polypeptide from NADH:ubiquinone oxidoreductase (Complex I) of beef-heart mitochondria. There is only one difference: the first cysteine residue is a leucine in the PSST subunit. The large nickel-binding subunit of nickel hydrogenases shows a surprising homology with the 49 kDa subunit of mitochondrial Complex I.
