Molybdopterin oxidoreductase, iron-sulfur binding subunit; Ferredoxins are iron-sulphur proteins that mediate electron transfer in a range of metabolic reactions; Contains 4 4Fe-4S type ferredoxin domains and a putatif Twin-arginine translocation pathway signal; Localized in the cytoplasmic membrane; Family membership.

Rieske [2Fe-2S] iron-sulfur protein; Protein that contains an unknown function N-terminal domain and a C-terminal Rieske [2Fe-2S] domain; The rieske domain has a [2Fe-2S] centre. Two conserved cysteines that one Fe ion while the other Fe ion is coordinated by two conserved histidines; Prokaryotic lipoprotein signal peptide cleaved between the residues 25 and 26; Localized in the outer membrane; Function unclear.

Associates with subunits I, II and IV to form cytochrome c oxidase the terminal enzyme of the respiratory chain; The functional role of subunit III is not yet understood; Contains five transmembrane segmemts; Localized in the cytoplasmic membrane; High confidence in function and specificity.

Cytochrome O ubiquinol oxidase, subunit III; Cytochrome O terminal oxidase complex is the component of the aerobic respiratory chain that predominates when cells are grown at high aeration; Heterooctamer of two A chains, two B chains, two C chains and two D chains; Contains five transmembrane segmemts; Localized in the cytoplasmic membrane; Family membership.

Conserved hypothetical lipoprotein; Protein containing a bacterial Ig-like domain 1 (Big-1). Big-1 domains (~95 amino acids) are usually present in bacterial adhesion molecules of the intimin/invasin family, involved in pathogenicity. Contains a prokaryotic lipoprotein signal peptide cleaved between the residues 25 and 26; Localized in the outer membrane; Conserved hypothetical protein.

OmpA-like periplasmic protein; This conserved protein contains a N-terminal module adopting a galactose-binding domain-like fold and a C-terminal OmpA-like domain. OmpA-like domains are thought to be responsible for non-covalent interactions with peptidoglycan; Signal peptide cleaved between the residues 24 and 25; Localized in the periplasmic space; Family membership.

GDSL-like Lipase; Conserved protein belonging to the GDSL Lipase family, which includes a variety of lipolytic enzymes with serine as part of the active site; Contains a N-terminal transmembrane helix; Localized in the cytoplasmic membrane; Family membership.

Glycosyltransferase, family GT4; Glycosyltransferase catalyses the transfer of sugar moieties from activated donor molecules to specific acceptor molecules, forming glycosidic bonds. Belongs to the family 4 of the glycosyltransferases. Localized in the cytoplasm; Specificity unclear.

Hypothetical periplasmic protein; Contains a signal peptide cleaved between the residues 18 and 19; Localized in the periplasmic space; Hypothetical protein.
