Putative sugar ABC transporter permease; Probably part of the binding-protein-dependent transport system YcjNOP. Probably responsible for the translocation of the substrate across the membrane; Belongs to the binding-protein-dependent transport system permease family. MalFG subfamily.

Putative NADH-binding oxidoreductase; Catalyzes the NADH-dependent reduction of the oxo group at C3 of 3-dehydro-D-glucosides leading to D-glucosides. Probably functions in a metabolic pathway that transforms D-gulosides to D-glucosides. Can use 3-dehydro-D-glucose, methyl alpha-3-dehydro-D-glucoside and methyl beta-3-dehydro-D-glucoside as substrates in vitro. However, the actual specific physiological substrates for this metabolic pathway are unknown. To a lesser extent, is also able to catalyze the reverse reactions, i.e. the NAD(+)-dependent oxidation of the hydroxyl group at C3 of [...]

Putative Zn-dependent NAD(P)-binding oxidoreductase; Catalyzes the NAD(+)-dependent oxidation of the hydroxyl group at C3 of D-gulosides leading to 3-dehydro-D-gulosides. Probably functions in a metabolic pathway that transforms D-gulosides to D- glucosides. Is also able to catalyze the reverse reactions, i.e. the NADH-dependent reduction of the oxo group at C3 of 3-dehydro-D- gulosides leading to D-gulosides. In vitro, can oxidize D-gulose and methyl beta-D-guloside, and reduce methyl alpha-3-dehydro-D-guloside and methyl beta-3-dehydro-D-guloside. However, the actual specific physiol [...]

Putative TIM alpha/beta barrel enzyme; Catalyzes the epimerization at C4 of 3-dehydro-D-gulosides leading to 3-dehydro-D-glucosides. Probably functions in a metabolic pathway that transforms D-gulosides to D-glucosides. Can use methyl alpha-3-dehydro-D-glucoside and methyl beta-3-dehydro-D-glucoside as substrates in vitro. However, the actual specific physiological substrates for this metabolic pathway are unknown. Cannot act on D- psicose, D-fructose, D-tagatose, D-sorbose, L-xylulose, or L-ribulose. Belongs to the hyi family.

Alpha amylase catalytic domain family protein; Catalyzes the reversible phosphorolysis of glucosylglycerate into alpha-D-glucose 1-phosphate (Glc1P) and D-glycerate (also called (R)-glycerate). May be a regulator of intracellular levels of glucosylglycerate, a compatible solute that primarily protects organisms facing salt stress and very specific nutritional constraints. Cannot catalyze the phosphorolysis of sucrose. Does not act on other sugars such as alpha-D-galactose 1-phosphate, alpha-D-mannose 1- phosphate or beta-D-glucose 1-phosphate; in vitro D-erythronate can substitue for D [...]

Putative family 65 glycosyl hydrolase; In vitro catalyzes the phosphorolysis of D-kojibiose into beta-D-glucose 1-phosphate and D-glucose. No other disaccharides tested substitute for D-kojibiose. In the reverse direction disaccharides can be formed from beta-D-glucose 1-phosphate plus D-glucose, L-sorbose, D- sorbitol, L-iditol or 1,5-anhydro-D-glucitol, but with low efficiency. The beta-D-glucose 1-phosphate product is the substrate for YcjU (AC P77366), the next apparent enzyme in the putative biochemical pathway encoded in this locus (yjcM to ycjW).

Sn-glycerol-3-phosphate ABC transporter permease; Part of the binding-protein-dependent transport system for sn-glycerol-3-phosphate; probably responsible for the translocation of the substrate across the membrane.

Sn-glycerol-3-phosphate ABC transporter ATPase; Part of the ABC transporter complex UgpABCE involved in sn- glycerol-3-phosphate import. Responsible for energy coupling to the transport system (Probable). Can also transport glycerophosphoryl diesters.

Maltose ABC transportor ATPase; Part of the ABC transporter complex MalEFGK involved in maltose/maltodextrin import. Responsible for energy coupling to the transport system; Belongs to the ABC transporter superfamily. Maltooligosaccharide importer (TC 3.A.1.1.1) family.
