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:
a 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

lyxKL-xylulose kinase; Catalyzes the phosphorylation of L-xylulose and 3-keto-L- gulonate. Is involved in L-lyxose utilization via xylulose, and may also be involved in the utilization of 2,3-diketo-L-gulonate. (498 aa)    
Predicted Functional Partners:
sgbU
Putative L-xylulose 5-phosphate 3-epimerase; Catalyzes the isomerization of L-xylulose-5-phosphate to L- ribulose-5-phosphate (Potential). May be involved in the utilization of 2,3-diketo-L-gulonate; Belongs to the L-ribulose-5-phosphate 3-epimerase family.
 
 0.999
sgbH
3-keto-L-gulonate 6-phosphate decarboxylase; Catalyzes the decarboxylation of 3-keto-L-gulonate-6-P into L-xylulose-5-P. May be involved in the utilization of 2,3-diketo-L- gulonate.
 
 0.998
yiaK
2,3-diketo-L-gulonate reductase, NADH-dependent; Catalyzes the reduction of 2,3-diketo-L-gulonate in the presence of NADH, to form 3-keto-L-gulonate.
 
 
 0.983
sgbE
L-ribulose-5-phosphate 4-epimerase; Catalyzes the interconversion of L-ribulose 5-phosphate (LRu5P) and D-xylulose 5-phosphate (D-Xu5P) via a retroaldol/aldol mechanism (carbon-carbon bond cleavage analogous to a class II aldolase reaction). May be involved in the utilization of 2,3-diketo-L-gulonate.
 
  
 0.974
ulaE
L-xylulose 5-phosphate 3-epimerase; Catalyzes the isomerization of L-xylulose-5-phosphate to L- ribulose-5-phosphate. Is involved in the anaerobic L-ascorbate utilization; Belongs to the L-ribulose-5-phosphate 3-epimerase family.
 
 0.974
ulaD
3-keto-L-gulonate 6-phosphate decarboxylase; Catalyzes the decarboxylation of 3-keto-L-gulonate-6-P into L-xylulose-5-P. Is involved in the anaerobic L-ascorbate utilization. Belongs to the HPS/KGPDC family. KGPDC subfamily.
 
 0.957
rhaB
Rhamnulokinase; Involved in the catabolism of L-rhamnose (6-deoxy-L-mannose). It could also play a role in the metabolism of some rare sugars such as L-fructose. Catalyzes the transfer of the gamma-phosphate group from ATP to the 1-hydroxyl group of L-rhamnulose to yield L-rhamnulose 1- phosphate. Uridine triphosphate (UTP), cytidine 5-triphosphate (CTP), guanosine 5-triphosphate (GTP), and thymidine triphosphate (TTP) also can act as phosphoryl donors. It can also phosphorylate L-fuculose and L-xylulose. Belongs to the rhamnulokinase family.
  
 
0.923
yiaM
2,3-diketo-L-gulonate TRAP transporter small permease protein; Part of the tripartite ATP-independent periplasmic (TRAP) transport system YiaMNO involved in the uptake of 2,3-diketo-L- gulonate.
 
  
 0.922
yiaO
2,3-diketo-L-gulonate-binding periplasmic protein; Part of the tripartite ATP-independent periplasmic (TRAP) transport system YiaMNO involved in the uptake of 2,3-diketo-L- gulonate. This protein specifically binds 2,3-diketo-L-gulonate. Is not able to bind either L-ascorbate or dehydroascorbate. Belongs to the bacterial solute-binding protein 7 family.
  
  
 0.919
ulaG
L-ascorbate 6-phosphate lactonase; Probably catalyzes the hydrolysis of L-ascorbate-6-P into 3- keto-L-gulonate-6-P. Is essential for L-ascorbate utilization under anaerobic conditions. Also shows phosphodiesterase activity, hydrolyzing phosphodiester bond in the artificial chromogenic substrate bis-p-nitrophenyl phosphate (bis-pNPP); Belongs to the UlaG family.
