STRINGSTRING
STRING protein interaction network
Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
some 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

ycjNPutative abc sugar transporter periplasmic binding protein; Probably part of the binding-protein-dependent transport system YcjNOP (430 aa)    
Predicted Functional Partners:
ycjO
Multiple sugar transport system permease protein; Probably part of the binding-protein-dependent transport system YcjNOP. Probably responsible for the translocation of the substrate across the membrane

ycjP
Multiple sugar transport system permease protein; Probably part of the binding-protein-dependent transport system YcjNOP. Probably responsible for the translocation of the substrate across the membrane

ycjR
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

ycjQ
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 [...]

ycjS
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 [...]

ycjM
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 fo [...]

ycjT
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)
 
   
 0.987
ycjU
Beta-phosphoglucomutase; Catalyzes the conversion of beta D-glucose 1-phosphate (G1P) to D-glucose 6-phosphate (G6P), forming beta-D-glucose 1,6- (bis)phosphate (beta-G16P) as an intermediate (Probable). Phosphatase activity with the reaction intermediate beta-G16P has been measured . In vitro interconverts beta D-glucose 1-phosphate, beta-D-allose 1-phosphate, beta-D-galactose 1-phosphate and beta-D-mannose 1-phosphate to their corresponding sugar 6-phosphate product. The beta-D-glucose 1-phosphate substrate may be furnished by YcjT (AC P77154), the apparent upstream enzyme in the put [...]
