STRINGSTRING
STRING protein interaction network
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

ilvAThreonine deaminase; 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). (427 aa)    
Predicted Functional Partners:
ilvN
Highly similar to many acetolactate synthases, small subunit, (EC 4.1.3.18) involved in valine and isoleucine biosynthesis, including: Mycobacterium avium SW:ILVH_MYCAV (Q59499) (167 aa); Fasta score E(): 0, 78.9% identity in 166 aa overlap and Mycobacterium tuberculosis RV3002C SW:ILVH_MYCTU (O53249) (168 aa); Fasta score E(): 0, 83.5% identity in 164 aa overlap. Contains Pfam match to entry PF01842 ACT, ACT domain.

ilvE
Putative branched-chain-amino-acid transaminase; Acts on leucine, isoleucine and valine; Belongs to the class-IV pyridoxal-phosphate-dependent aminotransferase family.
  
 
 0.957
glyA
Serine hydroxymethyltransferase; Catalyzes the reversible interconversion of serine and glycine with tetrahydrofolate (THF) serving as the one-carbon carrier. This reaction serves as the major source of one-carbon groups required for the biosynthesis of purines, thymidylate, methionine, and other important biomolecules. Also exhibits THF-independent aldolase activity toward beta-hydroxyamino acids, producing glycine and aldehydes, via a retro-aldol mechanism.
     
 0.950
thrC
Threonine synthase; Catalyzes the gamma-elimination of phosphate from L- phosphohomoserine and the beta-addition of water to produce L- threonine.

sdaA
Highly similar to many L-serine dehydratases (EC 4.2.1.13) including: Escherichia coli SW:TDCG_ECOLI (P42630) (454 aa); Fasta score E(): 0, 53.2% identity in 457 aa overlap and Mycobacterium tuberculosis RV0069 SW:SDHL_MYCTU (O53614) (461 aa); Fasta score E(): 0, 69.2% identity in 461 aa overlap; Belongs to the iron-sulfur dependent L-serine dehydratase family.
  
 
 0.949
leuB
3-isopropylmalate dehydrogenase; Catalyzes the oxidation of 3-carboxy-2-hydroxy-4- methylpentanoate (3-isopropylmalate) to 3-carboxy-4-methyl-2- oxopentanoate. The product decarboxylates to 4-methyl-2 oxopentanoate (By similarity); Belongs to the isocitrate and isopropylmalate dehydrogenases family. LeuB type 2 subfamily.
