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:
exbDtonB-dependent uptake of B colicins; similar to E. coli uptake of enterochelin; tonB-dependent uptake of B colicins (AAC76041.1); Blastp hit to AAC76041.1 (141 aa), 93% identity in aa 1 - 141. (141 aa)
fepASimilar to E. coli outer membrane receptor for ferric enterobactin (enterochelin) and colicins B and D (AAC73685.1); Blastp hit to AAC73685.1 (746 aa), 81% identity in aa 1 - 746. (751 aa)
ybdAPutative POT family transport protein; Component of an export pathway for enterobactin. Belongs to the major facilitator superfamily. EntS (TC 2.A.1.38) family. (414 aa)
fepBABC superfamily (peri_perm); similar to E. coli ferric enterobactin (enterochelin) binding protein; periplasmic component (AAC73693.1); Blastp hit to AAC73693.1 (318 aa), 79% identity in aa 1 - 318. (318 aa)
purRTranscriptional repressor for pur regulon, glyA, glnB, prsA, speA (GalR/LacI family); 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. PurR is allosterically activated to bind its cognate DNA by binding the purine corepressors, hypoxanthine or guanine, thereby effecting transcription repression. (341 aa)
tonBTonB; Interacts with outer membrane receptor proteins that carry out high-affinity binding and energy dependent uptake into the periplasmic space of specific substrates such as cobalamin, and various iron compounds (such as iron dicitrate, enterochelin, aerobactin, etc.). In the absence of TonB these receptors bind their substrates but do not carry out active transport. TonB also interacts with some colicins and is involved in the energy-dependent, irreversible steps of bacteriophages phi 80 and T1 infection. It could act to transduce energy from the cytoplasmic membrane to specific en [...] (242 aa)
mntHManganese/divalent cation transport protein; H(+)-stimulated, divalent metal cation uptake system. Involved in manganese and iron uptake; Belongs to the NRAMP family. (413 aa)
iroBPutative glycosyl transferase; Related to UDP-glucuronosyltransferase. (371 aa)
iroEPutative hydrolase of the alpha/beta superfamily. (311 aa)
exbBUptake of enterochelin; Involved in the TonB-dependent energy-dependent transport of various receptor-bound substrates. Protects ExbD from proteolytic degradation and functionally stabilizes TonB (By similarity). (244 aa)
feoASimilar to E. coli ferrous iron transport protein A (AAC76433.1); Blastp hit to AAC76433.1 (75 aa), 96% identity in aa 1 - 75. (75 aa)
feoBFerrous iron transport protein B; Probable transporter for a GTP-driven Fe(2+) uptake system. Belongs to the TRAFAC class TrmE-Era-EngA-EngB-Septin-like GTPase superfamily. FeoB GTPase (TC 9.A.8) family. (772 aa)
yhgGPutative cytoplasmic protein; May function as a transcriptional regulator that controls feoABC expression. (78 aa)
katGCatalase; Bifunctional enzyme with both catalase and broad-spectrum peroxidase activity; Belongs to the peroxidase family. Peroxidase/catalase subfamily. (726 aa)
