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

(188 aa)    
Predicted Functional Partners:
DIP1890
Putative cysteine synthase; Similar to the C-terminal region of Arabidopsis thaliana cysteine synthase, mitochondrial precursor ACS 1 SW:CYSM_ARATH (Q43725) (424 aa) fasta scores: E(): 1.5e-58, 53.39% id in 309 aa, and to the full length Neisseria meningitidis (serogroup A) putative cysteine synthase NMA0974 TR:Q9JQL6 (EMBL:AL162754) (310 aa) fasta scores: E(): 5.6e-65, 59.09% id in 308 aa.
 
 0.998
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.

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.
     
 0.904
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.
     
 0.904
cysS1
Similar to Escherichia coli cysteinyl-tRNA synthetase CysS or B0526 SW:SYC_ECOLI (P21888) (461 aa) fasta scores: E(): 2.4e-70, 44.11% id in 467 aa, and to Mycobacterium tuberculosis cysteinyl-tRNA synthetase 1 Rv3580c SW:SYC1_MYCTU (P96862) (469 aa) fasta scores: E(): 1.4e-120, 64.57% id in 463 aa; Belongs to the class-I aminoacyl-tRNA synthetase family.

DIP1863
Putative hydrolase; Similar to Mycobacterium tuberculosis hypothetical protein Rv3042c TR:AAK47457 (EMBL:AL021287) (409 aa) fasta scores: E(): 3.1e-69, 54.54% id in 407 aa, and to Mycobacterium leprae putative phosphoserine phosphatase ML1727 TR:Q9CBQ6 (EMBL:AL583923) (411 aa) fasta scores: E(): 6.2e-66, 53.82% id in 405 aa.

thrB
Homoserine kinase; Catalyzes the ATP-dependent phosphorylation of L-homoserine to L-homoserine phosphate; Belongs to the GHMP kinase family. Homoserine kinase subfamily.
     
 0.813
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.
