Microbial biochemistry has recently entered a new and interesting phase. Catabolic
pathways are being reported for the biodegradation of complex organic compounds some of …

Methyl-coenzyme M reductase (MCR) catalyzes the methane-forming step in methanogenic
archaea. The active enzyme harbors the nickel (I) hydrocorphin coenzyme F-430 as a …

Nickel, atomic no. 28, constitutes 8.5% of the earth's core and about 0.008% of the earth's
crust (139). Average worldwide nickel concentrations have been estimated to be 1.0, g/kg for …

Riboflavin (Vitamin B2) with its tricyclic isoalloxazine ring is perhaps the most versatile
biological redox reagent. In its 5'-phosphate (FMN) and S'-ADP (FAD) coenzymatic forms, it …

Three types of hydrogenases have been isolated from the sulfate-reducing bacteria of the
genus Desulfobibrio. They differ in their subunit and metal compositions, physico-chemical …

Methanobacterium thermoautotrophicum has been reported to require nickel for growth and
to contain high concentrations of a nickel tetrapyrrole designated factor F430. In this …

Approximately one-third of the known enzymes are metalloenzymes. The metal ions
promote a variety of reactions in these enzymes, including bond cleavage and formation …

Methyl-coenzyme M reductase (MCR) is the key enzyme of methanogenesis and anaerobic
methane oxidation. The activity of MCR is dependent on the unique nickel-containing …
