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

murIProbable glutamate racemase MurI; Provides the (R)-glutamate required for cell wall biosynthesis. (271 aa)    
Predicted Functional Partners:
murD
Probable UDP-N-acetylmuramoylalanine-D-glutamate ligase MurD; Cell wall formation. Catalyzes the addition of glutamate to the nucleotide precursor UDP-N-acetylmuramoyl-L-alanine (UMA). Belongs to the MurCDEF family.
 
 
 0.994
cysM
O-phosphoserine sulfhydrylase; Catalyzes the formation of a covalent CysO-cysteine adduct via a sulfur transfer, using the thiocarboxylated sulfur carrier protein CysO-COSH as sulfur donor and O-phospho-L-serine (OPS) as sulfur acceptor. Can also use sodium sulfide as sulfur donor in vitro, albeit with less efficiency, but not thiosulfate or thio-nitro- benzoate. O-acetylserine (OAS) is a very poor substrate in comparison with OPS. May be of particular importance for cysteine biosynthesis in the persistent phase of M.tuberculosis; Belongs to the cysteine synthase/cystathionine beta- sy [...]

Rv1337
Rv1337, (MTCY130.22), len: 240 aa. Probable integral membrane protein. Highly similar to P53426 hypothetical protein B1549_C3_240 from M.leprae (251); and P74553|D90916 hypothetical protein from Synechocystis sp. (198 aa), FASTA scores: E(): 2.3e-25, (43.6% identity in 181 aa overlap).
  
  
 0.966
Rv1341
Conserved protein; Pyrophosphatase that catalyzes the hydrolysis of nucleoside triphosphates to their monophosphate derivatives, with a high preference for the non-canonical purine nucleotides XTP (xanthosine triphosphate), dITP (deoxyinosine triphosphate) and ITP. Seems to function as a house-cleaning enzyme that removes non-canonical purine nucleotides from the nucleotide pool, thus preventing their incorporation into DNA/RNA and avoiding chromosomal lesions. Belongs to the HAM1 NTPase family.
 
    0.960
purQ
Probable phosphoribosylformylglycinamidine synthase I PURG (FGAM synthase I); Part of the phosphoribosylformylglycinamidine synthase complex involved in the purines biosynthetic pathway. Catalyzes the ATP-dependent conversion of formylglycinamide ribonucleotide (FGAR) and glutamine to yield formylglycinamidine ribonucleotide (FGAM) and glutamate. The FGAM synthase complex is composed of three subunits. PurQ produces an ammonia molecule by converting glutamine to glutamate. PurL transfers the ammonia molecule to FGAR to form FGAM in an ATP- dependent manner. PurS interacts with PurQ and [...]

mec
Possible hydrolase; Protease that hydrolyzes the covalent CysO-cysteine adduct synthesized by CysM to release L-cysteine and regenerate CysO.
  
    0.885
cysO
Sulfur carrier protein CysO; In its thiocarboxylated form (CysO-COSH), is the sulfur donor in the CysM-dependent cysteine biosynthetic pathway. May be of particular importance for cysteine biosynthesis in the persistent phase of M.tuberculosis; Belongs to the sulfur carrier protein CysO family.
  
    0.882
murG
Undecaprenyldiphospho-muramoylpentapeptide beta-N-acetylglucosaminyltransferase; Cell wall formation. Catalyzes the transfer of a GlcNAc subunit on undecaprenyl-pyrophosphoryl-MurNAc-pentapeptide (lipid intermediate I) to form undecaprenyl-pyrophosphoryl-MurNAc- (pentapeptide)GlcNAc (lipid intermediate II).
 
  
 0.881
Rv1333
Probable hydrolase; Aminopeptidase; Belongs to the peptidase S58 family.
  
    0.854
alr
Alanine racemase Alr; Catalyzes the interconversion of L-alanine and D-alanine. D- alanine plays a key role in peptidoglycan cross-linking.
