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.

Preprotein translocase subunit TatA; 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. TatA could form the protein-conducting channel of the Tat system.

Pseudouridine-5'-phosphate glycosidase; Catalyzes the reversible cleavage of pseudouridine 5'- phosphate (PsiMP) to ribose 5-phosphate and uracil. Functions biologically in the cleavage direction, as part of a pseudouridine degradation pathway; Belongs to the pseudouridine-5'-phosphate glycosidase family.

Ubiquinone biosynthesis protein UbiB; Is probably a protein kinase regulator of UbiI activity which is involved in aerobic coenzyme Q (ubiquinone) biosynthesis. Belongs to the ABC1 family. UbiB subfamily.

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

Guanylate kinase; Essential for recycling GMP and indirectly, cGMP.

Ubiquinone biosynthesis methyltransferase UbiE; Methyltransferase required for the conversion of demethylmenaquinol (DMKH2) to menaquinol (MKH2) and the conversion of 2-polyprenyl-6-methoxy-1,4-benzoquinol (DDMQH2) to 2-polyprenyl-3- methyl-6-methoxy-1,4-benzoquinol (DMQH2).

methionine--tRNA ligase; Is required not only for elongation of protein synthesis but also for the initiation of all mRNA translation through initiator tRNA(fMet) aminoacylation.
