Conserved hypothetical membrane protein; Contains an uncleavable signal sequence; Localized in the cytoplasmic membrane; Conserved hypothetical protein.

The sensor histidine kinase belongs to two-component signal transduction systems. It catalyzes the ATP dependent autophosphorylation of a conserved histidine in its phosphoacceptor domain and the signal dependent phosphorylation of a conserved aspartic acid present in the response regulator receiver domain. Contains two transmembrane segments. Localized in the cytoplasmic membrane; Specificity unclear.

Alpha-acetolactate decarboxylase is involved in ketone and acetoin biosynthesis. It converts acetolactate into acetoin: (S)-2-hydroxy-2-methyl-3-oxobutanoate = (R)-2-acetoin + CO2. Displays a C-terminal domain of unknown function. Features a signal peptide cleaved between the residues 20 and 21. Localized in the periplasm; High confidence in function and specificity.

Putative protein.

The ABC-1 type transporters have their ABC membrane domain and their ABC ATPase domain fused in the same protein. They are involved in the efflux of compounds across the biological membranes or in targeting of membrane components; Contains five N-terminal transmembrane segments (ABC membrane) that form a pore in the cytoplasmic membrane an a C-terminal ATP-binding domain (ABC ATPase) responsible for energy generation; Belongs to the ABC-1 type transporter permease/ATP-binding family, lipid exporter subfamily (msbA); Family membership.

Conserved hypothetical membrane protein; Contains three transmembrane helices; Localized in the cytoplasmic membrane; Conserved hypothetical protein.

TonB-dependent Receptor; Protein localized in the outer membrane involved in uptake of macromolecules that are too large to diffuse via the outer membrane porins channels or are encountered at very low concentrations; Contains a carboxypeptidase regulatory domain (50-125) and the Plug module (141-250) acting as a channel gate; The signal peptide is cleaved between the residues 34 and 35; Family membership.

The response regulator proteins are involved in the two-component signal transduction systems to detect and respond to environmental changes. These proteins consist of two domains, an N-terminal response regulator receiver domain that is substrate for a histidine protein kinase sensor, and a variable C-terminal effector domain with DNA-binding activity (here, a winged-helix DNA-binding domain) that acts as transcriptional regulator; Family membership.

SusD/RagB family lipoprotein; Protein probably involved in nutrient binding. This sequence corresponds to the N-terminal domain found in the proteins belonging to the SusD/RagB family; Contains a lipoprotein signal peptide cleaved between the residues 25 and 26; Probably localized in the outer membrane; Family membership.
