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.

metXHomoserine O-acetyltransferase; Transfers an acetyl group from acetyl-CoA to L-homoserine, forming acetyl-L-homoserine. (367 aa)    
Predicted Functional Partners:
DIP0630
Putative methionine biosynthesis-related protein; Similar to Mycobacterium tuberculosis CDC1551 transulfuration enzyme family protein MT3443 TR:AAK47787 (EMBL:AE007151) (449 aa) fasta scores: E(): 4.8e-93, 56.94% id in 432 aa, and to Pseudomonas aeruginosa O-succinylhomoserine sulfhydrylase MetZ or PA3107 SW:METZ_PSEAE (P55218) (403 aa) fasta scores: E(): 2.7e-26, 39.31% id in 435 aa.
 
 
 0.994
thrA
Similar to Corynebacterium glutamicum homoserine dehydrogenase Hom or ThrA SW:DHOM_CORGL (P08499) (445 aa) fasta scores: E(): 4.2e-117, 75.28% id in 437 aa, and to Bacillus subtilis homoserine dehydrogenase Hom or Tdm SW:DHOM_BACSU (P19582) (433 aa) fasta scores: E(): 4.2e-54, 40.18% id in 433 aa.
 
 
 0.952
thrB
Homoserine kinase; Catalyzes the ATP-dependent phosphorylation of L-homoserine to L-homoserine phosphate; Belongs to the GHMP kinase family. Homoserine kinase subfamily.
     
 0.908
lysC
Aspartokinase; Similar to Corynebacterium flavum aspartokinase LysC or Ask SW:AK_CORFL (P41398) (421 aa) fasta scores: E(): 1.8e-135, 87.64% id in 421 aa; Belongs to the aspartokinase family.
    
 0.875
ilvA
Threonine dehydratase biosynthetic; 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.
  
 
 0.831
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.
     
 0.820
DIP1199
Putative methyltransferase; Similar to, although longer in its N-terminal region than Mycobacterium tuberculosis putative methyltransferase Rv3342 or MT3445 or MTV016.42 SWALL:YX42_MYCTU (SWALL:O53392) (243 aa) fasta scores: E(): 2e-16, 31.71% id in 227 aa, and to Pseudomonas aeruginosa hypothetical protein PA0558 SWALL:Q9I5X8 (EMBL:AE004492) (255 aa) fasta scores: E(): 8.9e-11, 28.06% id in 253 aa.
  
  
 0.812
sdaA
L-serine dehydratase 1; Similar to Escherichia coli L-serine dehydratase 1 SdaA or B1814 SW:SDHL_ECOLI (P16095) (454 aa) fasta scores: E(): 4.8e-113, 63.08% id in 447 aa; Belongs to the iron-sulfur dependent L-serine dehydratase family.
     
 0.803
sdaB
L-serine dehydratase; Similar to Pseudomonas aeruginosa L-serine dehydratase SdaB or PA5379 SWALL:Q9HTI5 (EMBL:AE004950) (458 aa) fasta scores: E(): 3.5e-84, 53.99% id in 463 aa, and to Escherichia coli L-serine dehydratase 1 SdaA or B1814 SWALL:SDHL_ECOLI (SWALL:P16095) (454 aa) fasta scores: E(): 3e-70, 49.24% id in 461 aa; Belongs to the iron-sulfur dependent L-serine dehydratase family.
     
 0.803
metH
5-methyltetrahydrofolate--homocysteine methyltransferase; 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.
