Gene names
Name:cooS
Ordered Locus Names:MK0536
OrganismMethanopyrus kandleri (strain AV19 / DSM 6324 / JCM 9639 / NBRC 100938)
Taxonomic identifier190192 [NCBI]
Taxonomic lineageArchaeaEuryarchaeotaMethanopyriMethanopyralesMethanopyraceaeMethanopyrus

Protein attributes

Sequence length638 AA.
Sequence statusComplete.
Protein existenceInferred from homology

General annotation (Comments)

Catalytic activity

CO + H2O + A = CO2 + AH2.

Cofactor

Binds 3 4Fe-4S clusters per homodimer By similarity.

Binds 2 nickel-iron-sulfur clusters per homodimer By similarity.

Subunit structure

Homodimer By similarity.

Domain

Cluster B is an all-cysteinyl-liganded 4Fe4S cluster; cluster C is a mixed Ni-Fe-S cluster which appears to be the active site of CO oxidation. Cluster D is also an all-cysteinyl-liganded 4Fe4S cluster that bridges the two subunits of the CODH dimer By similarity.

Sequence similarities

Belongs to the Ni-containing carbon monoxide dehydrogenase family.

Caution

This protein lacks the conserved Cys in position 54; it is replaced by a Trp. It is therefore possible that the D-cluster is either altered or missing in this protein, which may not form homodimers.

Sequence caution

The sequence AAF86272.1 differs from that shown. Reason: Frameshift at positions 356, 372, 411 and 441.
