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

murIGlutamate racemase (murI); Provides the (R)-glutamate required for cell wall biosynthesis. (268 aa)    
Predicted Functional Partners:
murD
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.
 
  
 0.983
TP_0438
Conserved hypothetical 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.
 
  0.942
alr
Alanine racemase (alr); Catalyzes the interconversion of L-alanine and D-alanine. May also act on other amino acids; Belongs to the alanine racemase family.
 
   
 0.810
nadE
NH(3)-dependent NAD(+) synthetase (nadE); Catalyzes the ATP-dependent amidation of deamido-NAD to form NAD.
    
  0.712
apt
Adenine phosphoribosyltransferase (apt); Catalyzes a salvage reaction resulting in the formation of AMP, that is energically less costly than de novo synthesis.
     
 0.637
TP_0405
mcbG protein, putative; Similar to SP:P05530 GB:X07875 PID:41983 percent identity: 23.94; identified by sequence similarity; putative.
       0.627
ddl
D-alanine--D-alanine ligase (ddlA); Cell wall formation.
 
  
 0.623
TP_0404
Predicted coding region TP0404; Hypothetical protein; identified by Glimmer; putative.
     
 0.622
murF
UDP-N-acetylmuramoylalanyl-D-glutamyl-2, 6-diaminopimelate--D-alanyl-D-alanine ligase (murF); Involved in cell wall formation. Catalyzes the final step in the synthesis of UDP-N-acetylmuramoyl-pentapeptide, the precursor of murein; Belongs to the MurCDEF family. MurF subfamily.
 
   
 0.603
topA
DNA topoisomerase I (topA); Releases the supercoiling and torsional tension of DNA, which is introduced during the DNA replication and transcription, by transiently cleaving and rejoining one strand of the DNA duplex. Introduces a single-strand break via transesterification at a target site in duplex DNA. The scissile phosphodiester is attacked by the catalytic tyrosine of the enzyme, resulting in the formation of a DNA- (5'-phosphotyrosyl)-enzyme intermediate and the expulsion of a 3'-OH DNA strand. The free DNA strand then undergoes passage around the unbroken strand, thus removing D [...]
