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 to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
protein homology
Your Input:
Gene Fusion
rbsRDna-binding transcriptional dual regulator rbsr; 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 (330 aa)    
Predicted Functional Partners:
Ribokinase; 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
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
Ribose transport system atp-binding protein; Part of the ABC transporter complex RbsABC involved in ribose import. Responsible for energy coupling to the transport system
Ribose transport system permease protein; Part of the ABC transporter complex RbsABC involved in ribose import. Probably responsible for the translocation of the substrate across the membrane
CP4-6 prophage; ornithine carbamoyltransferase ArgF; Reversibly catalyzes the transfer of the carbamoyl group from carbamoyl phosphate (CP) to the N(epsilon) atom of ornithine (ORN) to produce L-citrulline, which is a substrate for argininosuccinate synthetase, the enzyme involved in the final step in arginine biosynthesis
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
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
Putative d,d-dipeptide abc transporter atp-binding subunit ddpf; Part of the ABC transporter complex DdpABCDF, which is probably involved in D,D-dipeptide transport . Probably responsible for energy coupling to the transport system
Uncharacterized HTH-type transcriptional regulator YdiP; Putative ARAC-type regulatory protein; Protein involved in transcription and regulation of transcription, DNA-dependent
Trehalose 6-phosphate-inducible trehalose regulon transcriptional repressor; Repressor of the treBC operon. It is able to bind trehalose- 6-phosphate and trehalose
