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

homHomoserine 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. (435 aa)    
Predicted Functional Partners:
asd
Asd protein; Aspartate-semialdehyde dehydrogenase, an enzyme involved in the biosynthesis of various amino acids from aspartate. Similar to sprot|DHAS_ECOLI (67%) and to trembl|Q845W2 (75%). Pfam: Semialdehyde dehydrogenase,dimerisation Pfam: Semialdehyde dehydrogenase, NAD binding; High confidence in function and specificity.
 
 0.993
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 [...]
 
 0.984
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.
  
 
 0.981
lysC
Aspartate kinase (AK) catalyzes the phosphorylation of aspartate. The product of this reaction can then be used in the biosynthesis of lysine or in the pathway leading to homoserine, which participates in the biosynthesis of threonine, isoleucine and methionine. Similar to trembl|Q8RU02 (80%) and to pir|C83531 (74%). Pfam (PF00696): Amino acid kinase family Pfam (PF01842): two ACT domain; High confidence in function and specificity; Belongs to the aspartokinase family.
 0.966
metX
Probable homoserine O-acetyltransferase; Transfers a succinyl group from succinyl-CoA to L-homoserine, forming succinyl-L-homoserine.
 
 0.965
dapA
Dihydrodipicolinate synthase; Catalyzes the condensation of (S)-aspartate-beta-semialdehyde [(S)-ASA] and pyruvate to 4-hydroxy-tetrahydrodipicolinate (HTPA).
 
 
 0.964
metZ
Cys/Met metabolism pyridoxal-phosphate-dependent enzyme; Catalyzes the formation of L-homocysteine from O-succinyl-L- homoserine (OSHS) and hydrogen sulfide.
 
 
 0.961
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.

ilvE2
Branched-chain-amino-acid transaminase; Acts on leucine, isoleucine and valine. Belongs to the class-IV pyridoxal-phosphate-dependent aminotransferase family.
  
 
 0.953
azo2193
Probable O-acetylhomoserine aminocarboxypropyltransferase. Homology to cysD of A. nidulans of 51% (sprot|CYSD_EMENI). Transforms O-acetylhomoserine into homocysteine. Pfam: Cys/Met metabolism PLP-dependent enzyme no signal peptide no TMHs; High confidence in function and specificity.
