Cardiolipin synthase 2; Catalyzes the phosphatidyl group transfer from one phosphatidylglycerol molecule to another to form cardiolipin (CL) (diphosphatidylglycerol) and glycerol. Can also catalyze phosphatidyl group transfer to water to form phosphatidate. Belongs to the phospholipase D family. Cardiolipin synthase subfamily. ClsB sub-subfamily.

GSH-dependent disulfide bond oxidoreductase; Exhibits a very robust glutathione (GSH)-dependent disulfide- bond reductase activity toward the model substrate, 2-hydroxyethyl disulfide; the actual physiological substrates are not known. Has also a low GSH-dependent hydroperoxidase activity toward cumene hydroperoxide, but does not reduce H(2)O(2), tert-butyl hydroperoxide, benzyl peroxide, or lauroyl peroxide. Exhibits little or no GSH transferase activity with most typical electrophilic substrates, and has no detectable transferase activity using glutathionylspermidine (GspSH) as the n [...]

Putative oxidoreductase; Belongs to the short-chain dehydrogenases/reductases (SDR) family.

Putative oxidoreductase.

Putative mannosyl-3-phosphoglycerate phosphatase.

Trehalose-6-phosphate synthase; Catalyzes the transfer of glucose from UDP-alpha-D-glucose (UDP-Glc) to D-glucose 6-phosphate (Glc-6-P) to form trehalose-6- phosphate. Acts with retention of the anomeric configuration of the UDP-sugar donor. Essential for viability of the cells at low temperatures and at elevated osmotic strength. Belongs to the glycosyltransferase 20 family.

Putative ABC transporter periplasmic binding protein; Part of an ABC transporter complex involved in low-affinity glycine betaine uptake. Binds glycine betaine with low affinity. Belongs to the OsmX family.

Cysteine desulfurase, stimulated by SufE; Cysteine desulfurases mobilize the sulfur from L-cysteine to yield L-alanine, an essential step in sulfur metabolism for biosynthesis of a variety of sulfur-containing biomolecules. Component of the suf operon, which is activated and required under specific conditions such as oxidative stress and iron limitation. Acts as a potent selenocysteine lyase in vitro, that mobilizes selenium from L- selenocysteine. Selenocysteine lyase activity is however unsure in vivo. Belongs to the class-V pyridoxal-phosphate-dependent aminotransferase family. Csd [...]

Cysteine sulfinate desulfinase; Catalyzes the removal of elemental sulfur and selenium atoms from L-cysteine, L-cystine, L-selenocysteine, and L-selenocystine to produce L-alanine, and transiently retains the released sulfur atom on a cysteine residue, in the form of a persulfide. Can also desulfinate L-cysteine sulfinate, which is the best substrate of the enzyme. Functions as a selenium delivery protein in the pathway for the biosynthesis of selenophosphate. Seems to participate in Fe/S biogenesis by recruiting the SufBCD-SufE proteins. Transfers sulfur to CsdE that increases the cys [...]
