Putative thiol:disulfide oxidoreductase. Homology to helX of R. casulata of 35% Periplasmic protein thiol:disulphide oxidoreductase is involved in the biogenesis of c-type cytochromes as well as in disulphide bond formation in some periplasmic proteins. Tigrfam: dsbE: periplasmic protein thiol:disulfide signal peptide no TMHs; High confidence in function and specificity.

Conserved hypothetical secreted protein. Homology to SMa0025 of S. meliloti of 46% pir|D95263(SRS). Pfam: Transglutaminase_like Superfamily signal peptide no TMHs; Conserved hypothetical protein.

Fmt protein; Attaches a formyl group to the free amino group of methionyl- tRNA(fMet). The formyl group appears to play a dual role in the initiator identity of N-formylmethionyl-tRNA by promoting its recognition by IF2 and preventing the misappropriation of this tRNA by the elongation apparatus; Belongs to the Fmt family.

Probable peptide deformylase; Removes the formyl group from the N-terminal Met of newly synthesized proteins. Requires at least a dipeptide for an efficient rate of reaction. N-terminal L-methionine is a prerequisite for activity but the enzyme has broad specificity at other positions.

Preprotein translocase SecY subunit; The central subunit of the protein translocation channel SecYEG. Consists of two halves formed by TMs 1-5 and 6-10. These two domains form a lateral gate at the front which open onto the bilayer between TMs 2 and 7, and are clamped together by SecE at the back. The channel is closed by both a pore ring composed of hydrophobic SecY resides and a short helix (helix 2A) on the extracellular side of the membrane which forms a plug. The plug probably moves laterally to allow the channel to open. The ring and the pore may move independently.

Probable heat shock protein GrpE; Participates actively in the response to hyperosmotic and heat shock by preventing the aggregation of stress-denatured proteins, in association with DnaK and GrpE. It is the nucleotide exchange factor for DnaK and may function as a thermosensor. Unfolded proteins bind initially to DnaJ; upon interaction with the DnaJ-bound protein, DnaK hydrolyzes its bound ATP, resulting in the formation of a stable complex. GrpE releases ADP from DnaK; ATP binding to DnaK triggers the release of the substrate protein, thus completing the reaction cycle. Several round [...]

InterPro:Uncharacterized protein family UPF0005 IPR006213; Bax_inhbtr1. IPR006214; UPF0005. Pfam:ZIP: Zinc transporter Probable glutamatereceptor Signal peptide present (SignalP predicted) and transmembrane helices 7 (TMHMM predicted) Pfam:PF01027; UPF0005; InterPro: Uncharacterized protein family UPF0005 2_A_01_02: Multidrug resistance protein; Specificity unclear.

ATP-dependent Hsl protease ATP-binding subunit; ATPase subunit of a proteasome-like degradation complex; this subunit has chaperone activity. The binding of ATP and its subsequent hydrolysis by HslU are essential for unfolding of protein substrates subsequently hydrolyzed by HslV. HslU recognizes the N-terminal part of its protein substrates and unfolds these before they are guided to HslV for hydrolysis.
