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
Your Input:
cytRAnti-activator for CytR-CRP nucleoside utilization regulon; This protein negatively controls the transcription initiation of genes such as deoCABD, udp, and cdd encoding catabolizing enzymes and nupC, nupG, and tsx encoding transporting and pore-forming proteins. Binds cytidine and adenosine as effectors. (341 aa)
craTranscriptional repressor-activator for carbon metabolism; Global transcriptional regulator, which plays an important role in the regulation of carbon metabolism. Activates transcription of genes encoding biosynthetic and oxidative enzymes (involved in Krebs cycle, glyoxylate shunt and gluconeogenesis, such as ppsA and fbp). Represses genes involved in sugar catabolism, such as fruB, pfkA, pykF and adhE. Binds asymmetrically to the two half-sites of its operator. (334 aa)
purRTranscriptional repressor, hypoxanthine-binding; Is the main repressor of the genes involved in the de novo synthesis of purine nucleotides, regulating purB, purC, purEK, purF, purHD, purL, purMN and guaBA expression. In addition, it participates in the regulation or coregulation of genes involved in de novo pyrimidine nucleotide biosynthesis, salvage and uptake (pyrC, pyrD, carAB and codBA), and of several genes encoding enzymes necessary for nucleotide and polyamine biosynthesis (prsA, glyA, gcvTHP, speA, glnB). Binds to a 16-bp palindromic sequence located within the promoter region [...] (341 aa)
galSGalactose- and fucose-inducible galactose regulon transcriptional isorepressor; Repressor of the mgl operon. Binds galactose and D-fucose as inducers. GalS binds to an operator DNA sequence within its own coding sequence (corresponding to residues 15 to 20). (346 aa)
galRGalactose-inducible d-galactose regulon transcriptional repressor; Repressor of the galactose operon. Binds galactose as an inducer. (343 aa)
rbsRTranscriptional 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. (330 aa)
