Cytochrome caa3 oxidase (subunit II); Subunits I and II form the functional core of the enzyme complex. Electrons originating in cytochrome c are transferred via heme a and Cu(A) to the binuclear center formed by heme a3 and Cu(B).

Flagellar motor switching and energizing phosphatase; Component of the flagellar switch. Binds CheY-P and increases its hydrolysis rate in vitro. May function constitutively to remove CheY-P around the flagellar switch to maintain an optimal level of CheY-P whereas CheC may function after addition of an attractant to cope with increased levels of CheY-P; Belongs to the FliN/MopA/SpaO family.

Polyketide synthase of type I; Involved in some intermediate steps for the synthesis of the antibiotic polyketide bacillaene which is involved in secondary metabolism.

Molecular chaperone; Acts as a chaperone; Belongs to the heat shock protein 70 family.

Assembly factor BSco of the Cu(A) site of cytochrome c oxidase; Necessary for insertion of copper into the active site of cytochrome c oxidase. May play a role in copper homeostasis or redox signaling; Belongs to the SCO1/2 family.

Alkyl hydroperoxide reductase (small subunit); Thiol-specific peroxidase that catalyzes the reduction of hydrogen peroxide and organic hydroperoxides to water and alcohols, respectively. Plays a role in cell protection against oxidative stress by detoxifying peroxides; Belongs to the peroxiredoxin family. AhpC/Prx1 subfamily.

Putative thiol-disulfide oxidoreductase with thioredoxin domain; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative enzyme.

Peptide methionine S-sulfoxide reductase; Has an important function as a repair enzyme for proteins that have been inactivated by oxidation. Catalyzes the reversible oxidation-reduction of methionine sulfoxide in proteins to methionine. May deal with oxidative damage to alpha/beta-type SASP in spores.
