STRING protein interaction network
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 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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
protein homology
Your Input:
Gene Fusion
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:
Ribose import permease protein RbsC; Part of the ABC transporter complex RbsABC involved in ribose import. Probably responsible for the translocation of the substrate across the membrane
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
Ribose import binding protein RbsB; 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
Ribose operon repressor; 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
Ribose import ATP-binding protein RbsA; 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
Ribose-phosphate pyrophosphokinase; 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)
Ribose-5-phosphate isomerase A; 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
Deoxyribose-phosphate aldolase; Catalyzes a reversible aldol reaction between acetaldehyde and D-glyceraldehyde 3-phosphate to generate 2-deoxy- D-ribose 5-phosphate; Belongs to the DeoC/FbaB aldolase family. DeoC type 2 subfamily
Phosphopentomutase; Phosphotransfer between the C1 and C5 carbon atoms of pentose; Belongs to the phosphopentomutase family
Phosphoglucomutase; This enzyme participates in both the breakdown and synthesis of glucose; Belongs to the phosphohexose mutase family
