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

thrHProbable homoserine kinase; ThrH encodes a protein with an in vivo homoserine-kinase-like activity in P. aeruginosa. Homoserine kinase,the product of the thrB gene, catalyzes an obligatory step of threonine biosynthesis. Similar trembl|Q9I2Y2 (62%). Pfam (PF00702): haloacid dehalogenase-like hydrolase; Function unclear. (203 aa)    
Predicted Functional Partners:
serC
Phosphoserine transaminase; Catalyzes the reversible conversion of 3- phosphohydroxypyruvate to phosphoserine and of 3-hydroxy-2-oxo-4- phosphonooxybutanoate to phosphohydroxythreonine.; Belongs to the class-V pyridoxal-phosphate-dependent aminotransferase family. SerC subfamily.
  
 
 0.966
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.
   
 0.955
hom
Homoserine dehydrogenase catalyzes NAD-dependent reduction of aspartate beta-semialdehyde into homoserine. This reaction is the third step in a pathway leading from aspartate to homoserine. Similar to TREMBL:Q9RAM9 (77%) and to pir|DEPSHA(PIR (Georgetown University) (56%). Pfam: Homoserine dehydrogenase; High confidence in function and specificity.
    
 0.913
metH
Probable methionine synthase; Catalyzes the transfer of a methyl group from methyl- cobalamin to homocysteine, yielding enzyme-bound cob(I)alamin and methionine. Subsequently, remethylates the cofactor using methyltetrahydrofolate.
    
 0.913
serB
Phosphoserine phosphatase, SerB, catalyzes the final step in serine biosynthesis in E. coli. It hydrolyses the phosphate group from phosphoserine to yield serine. Similar to trembl|Q82X56 (54%) and to sprot|SERB_ECOLI (37%). TIGRFAM: phosphoserine phosphatase SerB Pfam (PF00702): haloacid dehalogenase-like hydrolase; Specificity unclear.
  
  
 0.910
thrC
ThrC protein; Threonine synthase is involved in threonine biosynthesis. It catalyses the conversion of O-phospho-L-homoserine and water into L-threonine and orthophosphate,using pyridoxal phosphate as a cofactor. The pyridoxal-phosphate binding site is a Lys (K) residue. The enzyme is distantly related to the serine/threonine dehydratases which are also pyridoxal-phosphate dependent enzymes. Similar to trembl|Q8XZR7 (68%), to sprot|THRC_METGL (69%) and to sprot|THRC_PSEAE (42%). TIGRFAM: thrC, threonine synthase Pfam (PF00291): Pyridoxal-phosphate dependent enzyme; High confidence in f [...]
    
 0.910
thrB
Probable homoserine kinase. Homology to thrB of M. flagellum of 51% (sprot|KHSE_METFL). CATALYTIC ACTIVITY: ATP + L-homoserine = ADP + O-phospho-L-homoserine. Pfam: Aminoglycoside phosphotransferase no signal peptide no TMHs; High confidence in function and specificity; Belongs to the pseudomonas-type ThrB family.
     
 0.906
trpB
TrpB protein; The beta subunit is responsible for the synthesis of L- tryptophan from indole and L-serine.
   
 
 0.905
metZ
Cys/Met metabolism pyridoxal-phosphate-dependent enzyme; Catalyzes the formation of L-homocysteine from O-succinyl-L- homoserine (OSHS) and hydrogen sulfide.
   
 
 0.904
ilvA
Probable 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.
