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:
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. (424 aa)
thrCThreonine synthase (O-phospho-L-homoserine phosphate-lyase (adding water;L-threonine-forming)); O-Phospho-L-homoserine + H2O <=> L-Threonine + Orthophosphate / O-Phospho-4-hydroxy-L-threonine + H2O <=> 4-Hydroxy-L-threonine + Orthophosphate. (480 aa)
thrA/homL-Homoserine + NAD+ <=> L-Aspartate 4-semialdehyde + NADH + H+ and L-Homoserine + NADP+ <=> L-Aspartate 4-semialdehyde + NADPH + H+. (441 aa)
serB/thrHPhosphoserine phosphatase/homoserine phosphotransferase bifunctional protein; O-Phospho-L-serine + H2O <=> L-Serine + Orthophosphate and D-O-Phosphoserine + H2O <=> D-Serine + Orthophosphate. (207 aa)
trpB2Tryptophan synthase beta subunit; The beta subunit is responsible for the synthesis of L- tryptophan from indole and L-serine. (496 aa)
sdaAL-serine dehydratase (L-serine ammonia-lyase); L-Serine <=> Pyruvate + NH3 / alpha-Amino acid <=> 2-Oxo acid + NH3 L-Serine <=> 2-Aminoacrylate + H2O /; Belongs to the iron-sulfur dependent L-serine dehydratase family. (470 aa)
