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

ilvCAcetohydroxy-acid isomeroreductase; Involved in the biosynthesis of branched-chain amino acids (BCAA). Catalyzes an alkyl-migration followed by a ketol-acid reduction of (S)-2-acetolactate (S2AL) to yield (R)-2,3-dihydroxy-isovalerate. In the isomerase reaction, S2AL is rearranged via a Mg-dependent methyl migration to produce 3-hydroxy-3-methyl-2-ketobutyrate (HMKB). In the reductase reaction, this 2-ketoacid undergoes a metal-dependent reduction by NADPH to yield (R)-2,3-dihydroxy-isovalerate. (342 aa)
cypCFatty acid beta-hydroxylating cytochrome P450; Catalyzes the alpha- and beta-hydroxylation of myristic acid in the presence of hydrogen peroxide; Belongs to the cytochrome P450 family. (417 aa)
ilvEKetomethiobutyrate-branched-chain/aromatic amino acid aminotransferase; Transaminates branched-chain amino acids and ketoglutarate. Involved in the final step of the methionine regeneration pathway, where ketomethiobutyrate (KMTB) is converted to methionine via a transamination. The amino donor preference is isoleucine, leucine, valine, phenylalanine, and tyrosine; Belongs to the class-IV pyridoxal-phosphate-dependent aminotransferase family. (356 aa)

spxARedox-sensitive regulator enzyme; Interferes with activator-stimulated transcription by interaction with the RNA polymerase alpha-CTD.

codYTranscriptional regulator, GTP and BCAA-dependent; DNA-binding protein that represses the expression of many genes that are induced as cells make the transition from rapid exponential growth to stationary phase and sporulation. It is a GTP- binding protein that senses the intracellular GTP concentration as an indicator of nutritional limitations. At low GTP concentration it no longer binds GTP and stop to act as a transcriptional repressor. (259 aa)
ilvAThreonine dehydratase; Catalyzes the anaerobic formation of alpha-ketobutyrate and ammonia from threonine in a two-step reaction. The first step involved a dehydration of threonine and a production of enamine intermediates (aminocrotonate), which tautomerizes to its imine form (iminobutyrate). Both intermediates are unstable and short-lived. The second step is the nonenzymatic hydrolysis of the enamine/imine intermediates to form 2- ketobutyrate and free ammonia. In the low water environment of the cell, the second step is accelerated by RidA (By similarity). (422 aa)
