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

ulaAL-ascorbate-specific enzyme IIC permease component of PTS; The phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar PTS), a major carbohydrate active transport system, catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane. The enzyme II UlaABC PTS system is involved in ascorbate transport. Belongs to the UlaA family. (465 aa)    
Predicted Functional Partners:
ulaB
L-ascorbate-specific enzyme IIB component of PTS; The phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar PTS), a major carbohydrate active transport system, catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane. The enzyme II UlaABC PTS system is involved in ascorbate transport.

ulaC
L-ascorbate-specific enzyme IIA component of PTS; The phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar PTS), a major carbohydrate active transport system, catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane. The enzyme II UlaABC PTS system is involved in ascorbate transport.

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.
 
 0.998
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.
 
  
 0.978
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.
 
  
 0.972
ulaF
L-ribulose 5-phosphate 4-epimerase; Catalyzes the isomerization of L-ribulose 5-phosphate to D- xylulose 5-phosphate. Is involved in the anaerobic L-ascorbate utilization; Belongs to the aldolase class II family. AraD/FucA subfamily.
 
  
 0.949
ulaR
Transcriptional repressor for the L-ascorbate utilization divergent operon; Represses ulaG and the ulaABCDEF operon. Two ulaR binding sites have been identified in each promoter. Full activity requires simultaneous interaction of UlaR with both divergent promoters and seems to be dependent on repressor-mediated DNA loop formation, which is helped by the action of integration host factor.
 
  
 0.903
ptsH
Phosphohistidinoprotein-hexose phosphotransferase component of PTS system (Hpr); General (non sugar-specific) component of the phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar PTS). This major carbohydrate active-transport system catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane. The phosphoryl group from phosphoenolpyruvate (PEP) is transferred to the phosphoryl carrier protein HPr by enzyme I. Phospho-HPr then transfers it to the PTS EIIA domain.

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.
 
  
 0.864
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.
