Belongs to the TRAP transporter large permease family.
Part of the tripartite ATP-independent periplasmic (TRAP) transport system.
The complex comprises the extracytoplasmic solute receptor protein and the two transmembrane proteins.
Belongs to the N(4)/N(6)-methyltransferase family.
Belongs to the acyl-CoA dehydrogenase family.
Catalyzes the dehydrogenation of Glutaryl-CoA to glutaconyl-CoA.
Required for rescue of stalled ribosomes mediated by trans-translation. Binds to transfer-messenger RNA (tmRNA), required for stable association of tmRNA with ribosomes. tmRNA and SmpB together mimic tRNA shape, replacing the anticodon stem-loop with SmpB. tmRNA is encoded by the ssrA gene; the 2 termini fold to resemble tRNA(Ala) and it encodes a 'tag peptide', a short internal open reading frame. During trans-translation Ala-aminoacylated tmRNA acts like a tRNA, entering the A-site of stalled ribosomes, displacing the stalled mRNA. The ribosome then switches to translate the ORF on the tmRNA; the nascent peptide is terminated with the 'tag peptide' encoded by the tmRNA and targeted for degradation. The ribosome is freed to recommence translation, which seems to be the essential function of trans-translation.
Belongs to the ABC-4 integral membrane protein family. LolC/E subfamily.
Belongs to the leucine-binding protein family.
Belongs to the PEP-utilizing enzyme family.
General (non sugar-specific) component of the phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar PTS). This major carbohydrate active-transport system catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane. Enzyme I transfers the phosphoryl group from phosphoenolpyruvate (PEP) to the phosphoryl carrier protein (HPr).
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.
The Tat system comprises two distinct complexes: a TatABC complex, containing multiple copies of TatA, TatB and TatC subunits, and a separate TatA complex, containing only TatA subunits. Substrates initially bind to the TatABC complex, which probably triggers association of the separate TatA complex to form the active translocon.
Belongs to the NAD(P)-dependent epimerase/dehydratase family. HldD subfamily.
Catalyzes the interconversion between ADP-D-glycero-beta-D-manno-heptose and ADP-L-glycero-beta-D-manno-heptose via an epimerization at carbon 6 of the heptose.
Contains a large N-terminal NADP-binding domain, and a smaller C-terminal substrate-binding domain.
Belongs to the membrane fusion protein (MFP) (TC 8.A.1) family.
Belongs to the type-I restriction system S methylase family.
