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

rbsKRibokinase; Catalyzes the phosphorylation of ribose at O-5 in a reaction requiring ATP and magnesium. The resulting D-ribose-5-phosphate can then be used either for sythesis of nucleotides, histidine, and tryptophan, or as a component of the pentose phosphate pathway. Belongs to the carbohydrate kinase PfkB family. Ribokinase subfamily. (309 aa)    
Predicted Functional Partners:
rbsD
D-ribose pyranase; Catalyzes the interconversion of beta-pyran and beta-furan forms of D-ribose. It also catalyzes the conversion between beta- allofuranose and beta-allopyranose; Belongs to the RbsD / FucU family. RbsD subfamily.
 
 
 0.993
rbsR
Transcriptional repressor of ribose metabolism; Transcriptional repressor for the ribose rbsDACBK operon. RbsR binds to a region of perfect dyad symmetry spanning the rbs operon transcriptional start site. The affinity for the rbs operator is reduced by addition of ribose, consistent with ribose being the inducer of the operon.
  
 0.992
rbsC
D-ribose ABC transporter permease; Part of the ABC transporter complex RbsABC involved in ribose import. Probably responsible for the translocation of the substrate across the membrane.
 
  
 0.984
rbsB
D-ribose ABC transporter periplasmic binding protein; Part of the ABC transporter complex RbsABC involved in ribose import. Binds ribose. Also serves as the primary chemoreceptor for chemotaxis; Belongs to the bacterial solute-binding protein 2 family.
 
  
 0.982
prs
Phosphoribosylpyrophosphate synthase; Involved in the biosynthesis of the central metabolite phospho-alpha-D-ribosyl-1-pyrophosphate (PRPP) via the transfer of pyrophosphoryl group from ATP to 1-hydroxyl of ribose-5-phosphate (Rib- 5-P).
   
 0.971
rbsA
D-ribose ABC transporter ATPase; Part of the ABC transporter complex RbsABC involved in ribose import. Responsible for energy coupling to the transport system. Belongs to the ABC transporter superfamily. Ribose importer (TC 3.A.1.2.1) family.
 
  
 0.957
rpiA
Ribose 5-phosphate isomerase, constitutive; Involved in the first step of the non-oxidative branch of the pentose phosphate pathway. It catalyzes the reversible conversion of ribose-5-phosphate to ribulose 5-phosphate. Can also act on D-ribose-5- diphosphate and D-ribose-5-triphosphate as substrate.
   
 0.951
rpiB
Ribose 5-phosphate isomerase B/allose 6-phosphate isomerase; Catalyzes the interconversion of ribulose-5-P and ribose-5-P. It probably also has activity on D-allose 6-phosphate.
  
 
 0.944
tktA
Transketolase 1, thiamine triphosphate-binding; Catalyzes the transfer of a two-carbon ketol group from a ketose donor to an aldose acceptor, via a covalent intermediate with the cofactor thiamine pyrophosphate. Thus, catalyzes the reversible transfer of a two-carbon ketol group from sedoheptulose-7-phosphate to glyceraldehyde-3-phosphate, producing xylulose-5-phosphate and ribose- 5-phosphate.
   
 0.922
tktB
Transketolase 2, thiamine triphosphate-binding; Catalyzes the reversible transfer of a two-carbon ketol group from sedoheptulose-7-phosphate to glyceraldehyde-3-phosphate, producing xylulose-5-phosphate and ribose-5-phosphate. Catalyzes the transfer of a two-carbon ketol group from a ketose donor to an aldose acceptor, via a covalent intermediate with the cofactor thiamine pyrophosphate (By similarity).
