Trifunctional NAD biosynthesis/regulator protein NadR; This enzyme has three activities: DNA binding, nicotinamide mononucleotide (NMN) adenylyltransferase and ribosylnicotinamide (RN) kinase. The DNA-binding domain binds to the nadB operator sequence in an NAD- and ATP-dependent manner. As NAD levels increase within the cell, the affinity of NadR for the nadB operator regions of nadA, nadB, and pncB increases, repressing the transcription of these genes. The RN kinase activity catalyzes the phosphorylation of RN to form nicotinamide ribonucleotide. The NMN adenylyltransferase activity [...]

MFS transporter family protein; Putative resistance protein (transport); Belongs to the major facilitator superfamily.

N-acetyl glucosamine specific PTS enzyme IIC, IIB, and IIA components; The phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar PTS), a major carbohydrate active transport system, catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane. This system is involved in N-acetylglucosamine transport. It can also transport and phosphorylate the antibiotic streptozotocin. Could play a significant role in the recycling of peptidoglycan.

Uncharacterized HTH-type transcriptional regulator YidP; Pseudogene, arbutin specific enzyme IIC component of PTS;enzyme; Transport of small molecules: Carbohydrates, organic acids, alcohols; PTS system, arbutin-like IIB component; PTS system, arbutin-like IIC component.

Putative DNA-binding transcriptional regulator of phosphonate uptake and biodegradation; Belongs to an operon involved in alkylphosphonate uptake and C-P lyase. Exact function not known. By similarity could be a transcriptional regulator.

GTP-binding protein; A 50S ribosomal subunit assembly protein with GTPase and nucleotide-independent chaperone activity. Genetic and deletion evidence suggests this is involved in ribosome assembly at low temperatures; it may also affect translation (Probable). Involved in incorporation of ribosomal protein L6 into precursor 44S ribosomal particles at low temperatures. Also has chaperone activity which does not require nucleotides. Binds GDP, ppGpp and GDPCP (a nonhydrolyzable GTP analog) with similar affinity; the conformation of the protein does not significantly change upon nucleoti [...]

Fused beta-glucoside-specific PTS enzymes: IIA component/IIB component/IIC component; The phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar PTS), a major carbohydrate active -transport system, catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane. This system is involved in beta-glucoside transport.

Repressor for the divergent puu operons, putrescine inducible; Represses puuA, puuD and puuP.

Nucleoside channel, receptor of phage T6 and colicin K; Functions as substrate-specific channel for nucleosides and deoxynucleosides. Has a greater affinity for deoxynucleosides than for nucleosides, and does not transport free bases. In addition, constitutes the receptor for colicin K and phage T6. Belongs to the nucleoside-specific channel-forming outer membrane porin (Tsx) (TC 1.B.10) family.
