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

NAD(+) synthase (glutamine-hydrolyzing); Catalyzes the ATP-dependent amidation of deamido-NAD to form NAD. Uses L-glutamine as a nitrogen source.

Conserved hypothetical protein; Bifunctional enzyme that catalyzes the epimerization of the S- and R-forms of NAD(P)HX and the dehydration of the S-form of NAD(P)HX at the expense of ADP, which is converted to AMP. This allows the repair of both epimers of NAD(P)HX, a damaged form of NAD(P)H that is a result of enzymatic or heat-dependent hydration. Catalyzes the epimerization of the S- and R-forms of NAD(P)HX, a damaged form of NAD(P)H that is a result of enzymatic or heat-dependent hydration. This is a prerequisite for the S-specific NAD(P)H-hydrate dehydratase to allow the repair o [...]

Gluconolactonase precursor (D-glucono-delta-lactone lactonohydrolase).HYDROLYZES THE GLUCONOLACTONE FORMED BY GLUCOSE-FRUCTOSE OXIDOREDUCTASE AND THAT FORMED IN AEROBIC CONDITIONS BY THE GLUCOSE DEHYDROGENASE PRESENT. 30% SMP-30. Pfam:PF03758; SMP-30; 1. Signal peptide: present; High confidence in function and specificity.

biotin--[acetyl-CoA-carboxylase] ligase; BirA bifunctional protein [Includes: Biotin operon repressor; Biotin--[acetyl-CoA-carboxylase] synthetase (EC 6.3.4.15) (Biotin--protein ligase)]. birA acts both as a biotin-operon repressor and as the enzyme that synthesizes the corepressor, acetyl-coa:carbon- dioxide ligase. this protein also activates biotin to form biotinyl-5'-adenylate and transfers the biotin moiety to biotin-accepting proteins. InterPro: Biotin--acetyl-CoA-carboxylase ligase birA_ligase: biotin--acetyl-CoA-carboxyla; Specificity unclear.

25-diketo-D-gluconic acid reductase B (EC 1.1.1.274) (25-DKG reductase B) (25-DKGR B) (25DKGR-B) (AKR5D). TREMBL:Q8Y090: 67% identity, 78% similarity. Catalyzes the reduction of 25-diketo-D-gluconic acid (25DKG) to 2-keto-L-gulonic acid (2KLG) (By similarity). subunit:monomer (by similarity). subcellular location:cytoplasmic (by similarity). 2-keto-l-gulonic acid is a key intermediate in the production of l-ascorbic acid (vitamin c). belongs to the aldo/keto reductase family InterPro:IPR001395; Aldo/ket_red. Pfam:PF00248; aldo_ket_red; 1. PRINTS PR00069; ALDKETRDTAS ribH: riboflavin sy [...]

DNA-directed RNA polymerase; Promotes RNA polymerase assembly. Latches the N- and C- terminal regions of the beta' subunit thereby facilitating its interaction with the beta and alpha subunits.

Conserved hypothetical protein; Binds the second messenger bis-(3'-5') cyclic dimeric guanosine monophosphate (c-di-GMP). Can bind two c-di-GMP molecules per monomer. May play a role in bacterial second-messenger regulated processes. Binding to c-di-GMP induces a conformational change of the C- and N-termini resulting in the exposure of a highly negative surface on one side of the protein to a possible effector protein.

Guanosine-3',5'-bis(diphosphate) 3'-diphosphatase; In eubacteria ppGpp (guanosine 3'-diphosphate 5-' diphosphate) is a mediator of the stringent response that coordinates a variety of cellular activities in response to changes in nutritional abundance.
