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

(Microbial infection) A mixed OmpC-OmpF heterotrimer is the outer membrane receptor for toxin CdiA-EC536; polymorphisms in extracellular loops 4 and 5 of OmpC confer susceptibility to CdiA- EC536-mediated toxicity; Belongs to the Gram-negative porin family. (362 aa)
lrpLeucine-responsive global transcriptional regulator; Mediates a global response to leucine. Exogenous leucine affects the expression of a number of different operons; lrp mediates this effect for at least some of these operons.

hcpHybrid-cluster [4Fe-2S-2O] subunit of anaerobic terminal reductases; Catalyzes the reduction of hydroxylamine to form NH(3) and H(2)O. Is also able to reduce hydroxylamine analogs such as methylhydroxylamine and hydroxyquinone. Might have a role as a scavenger of potentially toxic by-products of nitrate metabolism. Belongs to the HCP family. (550 aa)

pdhRPyruvate dehydrogenase complex repressor; Transcriptional repressor for the pyruvate dehydrogenase complex genes aceEF and lpd. (254 aa)
uidCPutative outer membrane porin for beta-glucuronides porin protein; Enhances the activity of the UidB (GusB) glucuronide transporter, on its own however it has no transport activity. Glucuronide transport does not occur in strain K12 due to a variant at position 100 of the UidB (GusB, AC P0CE44, AC P0CE45) protein. (421 aa)
fumAFumarate hydratase (fumarase A), aerobic Class I; Catalyzes the reversible hydration of fumarate to (S)-malate. Functions as an aerobic enzyme in the direction of malate formation as part of the citric acid cycle. Accounts for about 80% of the fumarase activity when the bacteria grow aerobically. To a lesser extent, also displays D-tartrate dehydratase activity in vitro, but is not able to convert (R)-malate, L-tartrate or meso-tartrate. Can also catalyze the isomerization of enol- to keto-oxaloacetate. (548 aa)

hisJHistidine ABC transporter periplasmic binding protein; Part of the histidine permease ABC transporter. Binds histidine. Interacts with HisQMP and stimulates ATPase activity of HisP, which results in histidine translocation (By similarity). (260 aa)
norRAnaerobic nitric oxide reductase DNA-binding transcriptional activator; Required for the expression of anaerobic nitric oxide (NO) reductase, acts as a transcriptional activator for at least the norVW operon. Activation also requires sigma-54. Not required for induction of the aerobic NO-detoxifying enzyme NO dioxygenase.
