K+/H+ antiporter for K+ efflux; Required for activity of the potassium/proton antiporter KhtU. Involved in protection of the cell from methylglyoxal, a toxic by-product of glycolysis.

Conserved hypothetical protein; Evidence 4: Homologs of previously reported genes of unknown function; PubMedId: 11985717.

Thiamine-phosphate pyrophosphorylase; Condenses 4-methyl-5-(beta-hydroxyethyl)thiazole monophosphate (THZ-P) and 2-methyl-4-amino-5-hydroxymethyl pyrimidine pyrophosphate (HMP-PP) to form thiamine monophosphate (TMP). Is also able to use the 2-methoxy analog MeO-HMP-PP, as substrate in vitro, but not the 2-trifluoromethyl analog CF(3)-HMP-PP. Belongs to the thiamine-phosphate synthase family.

Potassium transporter ATPase; Integral membrane subunit of the KtrAB potassium uptake transporter. The 2 major potassium transporter complexes KtrAB and KtrCD confer resistance to both suddenly imposed and prolonged osmotic stress.

RNA-binding Sun protein; Specifically methylates the cytosine at position 967 (m5C967) of 16S rRNA.

K+-transporting ATPase; Integral membrane subunit of the KtrCD potassium uptake transporter. The 2 major potassium transporter complexes KtrAB and KtrCD confer resistance to both suddenly imposed and prolonged osmotic stress; Belongs to the TrkH potassium transport family. Ktr (TC 2.A.38.4) subfamily.

Thiazole tautomerase; Catalyzes the irreversible aromatization of 2-((2R,5Z)-2- carboxy-4-methylthiazol-5(2H)-ylidene)ethyl phosphate (cThz*-P) to 2- (2-carboxy-4-methylthiazol-5-yl)ethyl phosphate (cThz-P), a step in the biosynthesis of the thiazole phosphate moiety of thiamine. Cannot use cThz* as substrate, indicating that the phosphate group is essential. Has no thiamine phosphate synthase activity, despite a high sequence similarity with ThiE.

Phosphorylated protein phosphatase E and diadenosine-polyphosphate hydrolase; Asymmetrically hydrolyzes Ap4p to yield AMP and ATP. Does not hydrolyze Ap2a or Ap6A. Also has an ATPase activity. Was shown to dephosphorylate phosphotyrosine but not phosphoserine or phosphothreonine from phosphorylated peptides. Involved in spore germination by controlling expression of genes coding for GerA and GerK receptors.

Flagellar hook protein; Evidence 2a: Function of homologous gene experimentally demonstrated in an other organism; Product type f: factor; Belongs to the flagella basal body rod proteins family.
