Thiosulfate reductase, putative; Identified by similarity to SP:P37600; match to protein family HMM PF00384; match to protein family HMM PF01568; match to protein family HMM PF04879.

Molybdopterin oxidoreductase, molybdopterin-binding subunit, putative; Component of the respiratory Qrc complex, that catalyzes the reduction of the menaquinone pool using electrons transferred from the reduced periplasmic cytochrome c3, and which is probably involved in sulfate respiration. Is likely essential for growth on H(2) or formate since the periplasmic hydrogenases and/or formate dehydrogenases act as primary electron donors for the Qrc complex. The function of the QrcB subunit is unknown; in the absence of a catalytic site, it may provide a structural scaffold for the other [...]

Molybdopterin oxidoreductase domain protein; Identified by match to protein family HMM PF00384; match to protein family HMM PF04879; Belongs to the prokaryotic molybdopterin-containing oxidoreductase family.

Ribonuclease HI; Endonuclease that specifically degrades the RNA of RNA-DNA hybrids.

Hypothetical protein; Identified by Glimmer2; putative.

Reductase, transmembrane subunit, putative; Identified by match to protein family HMM PF03916.

Iron-sulfur protein CooF; Identified by similarity to SP:P31894; match to protein family HMM PF00037.

Formate dehydrogenase, alpha subunit, selenocysteine-containing; Alpha chain of the formate dehydrogenase (FDH) that catalyzes the reversible two-electron oxidation of formate to carbon dioxide. The alpha subunit of formate dehydrogenase forms the active site.

Formate dehydrogenase, alpha subunit, selenocysteine-containing; Selenoprotein; identified by similarity to SP:P24183; match to protein family HMM PF00384; match to protein family HMM PF01568; match to protein family HMM PF04879; match to protein family HMM TIGR01409; match to protein family HMM TIGR01553; Belongs to the prokaryotic molybdopterin-containing oxidoreductase family.
