Thiosulfate sulfurtransferase; Catalyzes, although with low efficiency, the sulfur transfer reaction from thiosulfate to cyanide.

Transcriptional regulator; Represses the glpD, glpFK, glpTQ, and glpACB operons involved in glycerol-3-phosphate metabolism; Derived by automated computational analysis using gene prediction method: Protein Homology.

5-formyltetrahydrofolate cyclo-ligase; ygfA expression increases five to eight fold in Escherichia coli cells growing as biofilms; unknown function; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the 5-formyltetrahydrofolate cyclo-ligase family.

Preprotein translocase subunit SecE; Part of the twin-arginine translocation (Tat) system that transports large folded proteins containing a characteristic twin- arginine motif in their signal peptide across membranes. TatE shares overlapping functions with TatA; Belongs to the TatA/E family. TatE subfamily.

anti-RNA polymerase sigma factor SigE; An anti-sigma factor for extracytoplasmic function (ECF) sigma factor sigma-E (RpoE). ECF sigma factors are held in an inactive form by an anti-sigma factor until released by regulated intramembrane proteolysis (RIP). RIP occurs when an extracytoplasmic signal triggers a concerted proteolytic cascade to transmit information and elicit cellular responses. The membrane-spanning regulatory substrate protein is first cut periplasmically (site-1 protease, S1P, DegS), then within the membrane itself (site-2 protease, S2P, RseP), while cytoplasmic protea [...]

ATP-dependent metalloprotease; Acts as a processive, ATP-dependent zinc metallopeptidase for both cytoplasmic and membrane proteins. Plays a role in the quality control of integral membrane proteins; Belongs to the AAA ATPase family. In the central section; belongs to the AAA ATPase family.

Hypothetical protein; Derived by automated computational analysis using gene prediction method: Protein Homology.

Preprotein translocase; Part of the twin-arginine translocation (Tat) system that transports large folded proteins containing a characteristic twin- arginine motif in their signal peptide across membranes. Together with TatC, TatB is part of a receptor directly interacting with Tat signal peptides. TatB may form an oligomeric binding site that transiently accommodates folded Tat precursor proteins before their translocation.

tRNA s(4)U8 sulfurtransferase; Catalyzes the ATP-dependent transfer of a sulfur to tRNA to produce 4-thiouridine in position 8 of tRNAs, which functions as a near-UV photosensor. Also catalyzes the transfer of sulfur to the sulfur carrier protein ThiS, forming ThiS-thiocarboxylate. This is a step in the synthesis of thiazole, in the thiamine biosynthesis pathway. The sulfur is donated as persulfide by IscS.
