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

ycjMCatalyzes 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-glycerate with a much lower efficiency (559 aa)    
Predicted Functional Partners:
ycjN
Probably part of the binding-protein-dependent transport system YcjNOP
 
   
 0.989
ycjO
Probably part of the binding-protein-dependent transport system YcjNOP. Probably responsible for the translocation of the substrate across the membrane
 
   
 0.975
ycjT
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)
 
  
 0.975
ycjR
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.

ycjP
Probably part of the binding-protein-dependent transport system YcjNOP. Probably responsible for the translocation of the substrate across the membrane
 
   
 0.968
ycjU
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 (PubMed:16990279, PubMed:29684280) (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 [...]

ycjS
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 D-glucosides leading to 3-dehydro-D-g [...]

ycjQ
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 physiological substrates for this metabolic pathway are unknown.
