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

xylFD-xylose transporter subunit; Involved in the high-affinity D-xylose membrane transport system. Binds with high affinity to xylose. (330 aa)    
Predicted Functional Partners:
xylG
D-xylose ABC transporter dual domain ATPase; Part of the ABC transporter complex XylFGH involved in xylose import. Responsible for energy coupling to the transport system (Probable). The XylFGH system can also transport ribose in absence of xylose; Belongs to the ABC transporter superfamily. Xylose importer (TC 3.A.1.2.4) family.
 
 0.999
xylH
D-xylose ABC transporter permease; Part of the binding-protein-dependent transport system for D- xylose. Probably responsible for the translocation of the substrate across the membrane; Belongs to the binding-protein-dependent transport system permease family. AraH/RbsC subfamily.
 
 0.999
xylA
D-xylose isomerase; Protein involved in carbohydrate catabolic process and glucose metabolic process; Belongs to the xylose isomerase family.
 
  
 0.978
xylR
Xylose divergent operon transcriptional activator; Regulatory protein for the xylBAFGHR operon.
 
   
 0.952
xylB
Xylulokinase; Catalyzes the phosphorylation of D-xylulose to D-xylulose 5- phosphate. Also catalyzes the phosphorylation of 1- deoxy-D-xylulose to 1-deoxy-D-xylulose 5-phosphate, with lower efficiency. Can also use D-ribulose, xylitol and D- arabitol, but D-xylulose is preferred over the other substrates. Has a weak substrate-independent Mg-ATP-hydrolyzing activity ; Belongs to the FGGY kinase family.
 
  
 0.924
xylE
D-xylose transporter; Uptake of D-xylose across the boundary membrane with the concomitant transport of protons into the cell (symport system). Glucose is not transported, but can compete for xylose binding sites and can inhibit xylose transport (in vitro). Belongs to the major facilitator superfamily. Sugar transporter (TC 2.A.1.1) family.
   
  
 0.892
yjfF
Putative sugar ABC transporter permease; Part of the ABC transporter complex YtfQRT-YjfF involved in galactofuranose transport (Probable). Probably responsible for the translocation of the substrate across the membrane (Probable).
 
 0.871
ytfT
Putative sugar ABC transporter permease; Part of the ABC transporter complex YtfQRT-YjfF involved in galactofuranose transport (Probable). Probably responsible for the translocation of the substrate across the membrane (Probable). Belongs to the binding-protein-dependent transport system permease family. AraH/RbsC subfamily.
 
 
 0.840
lsrD
Autoinducer 2 import system permease protein; Part of the ABC transporter complex LsrABCD involved in autoinducer 2 (AI-2) import. Probably responsible for the translocation of the substrate across the membrane (Probable). Belongs to the binding-protein-dependent transport system permease family. AraH/RbsC subfamily.
 
 
 0.839
lsrB
Autoinducer 2-binding protein; Part of the ABC transporter complex LsrABCD involved in autoinducer 2 (AI-2) import. Binds AI-2 and delivers it to the LsrC and LsrD permeases (Probable); Belongs to the bacterial solute-binding protein 2 family.
