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.

thrCThreonine synthase; Catalyzes the gamma-elimination of phosphate from L- phosphohomoserine and the beta-addition of water to produce L- threonine. (352 aa)    
Predicted Functional Partners:
thrB
Homoserine kinase; Catalyzes the ATP-dependent phosphorylation of L-homoserine to L-homoserine phosphate; Belongs to the GHMP kinase family. Homoserine kinase subfamily.
  
 
 0.994
ilvA
Threonine 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.

hom
Homoserine dehydrogenase; Identified by match to protein family HMM PF00742; match to protein family HMM PF01842; match to protein family HMM PF03447.
 
 
 0.957
pdxA
4-hydroxythreonine-4-phosphate dehydrogenase; Identified by match to protein family HMM PF04166; match to protein family HMM TIGR00557; Belongs to the PdxA family.
    
  0.901
sync_0075
Asparate kinase, monofunctional class; Identified by similarity to SP:P08495; match to protein family HMM PF00696; match to protein family HMM PF01842; match to protein family HMM TIGR00656; match to protein family HMM TIGR00657.
  
 
 0.846
leuD
3-isopropylmalate dehydratase, small subunit; Catalyzes the isomerization between 2-isopropylmalate and 3- isopropylmalate, via the formation of 2-isopropylmaleate. Belongs to the LeuD family. LeuD type 1 subfamily.
  
  
 0.796
sync_2944
Hypothetical protein; Identified by Glimmer2; putative.
       0.773
ilvC
Ketol-acid reductoisomerase; 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.

sync_0387
Ferredoxin-dependent glutamate synthase, Fd-GOGAT; Identified by match to protein family HMM PF00310; match to protein family HMM PF00478; match to protein family HMM PF01493; match to protein family HMM PF01645; match to protein family HMM PF04898.

hisIE
Histidine biosynthesis bifunctional protein HisIE; Identified by similarity to SP:O34912; match to protein family HMM PF01502; match to protein family HMM PF01503; In the N-terminal section; belongs to the PRA-CH family.
