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. (269 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.
 
  
 0.955
HI_0260
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.
 
 
  0.906
purL
Phosphoribosylformylglycinamidine synthase (purL); Phosphoribosylformylglycinamidine synthase involved in the purines biosynthetic pathway. Catalyzes the ATP-dependent conversion of formylglycinamide ribonucleotide (FGAR) and glutamine to yield formylglycinamidine ribonucleotide (FGAM) and glutamate.
    
  0.726
guaB
Inosine-5'-monophosphate dehydrogenase (guaB); Catalyzes the conversion of inosine 5'-phosphate (IMP) to xanthosine 5'-phosphate (XMP), the first committed and rate-limiting step in the de novo synthesis of guanine nucleotides, and therefore plays an important role in the regulation of cell growth. Belongs to the IMPDH/GMPR family.
    
 0.706
HI_0221.1
Predicted coding region HI0221.1; Brute Force ORF; identified by GeneMark; putative; Belongs to the IMPDH/GMPR family.
    
 0.702
recG
ATP-dependent DNA helicase (recG); Critical role in recombination and DNA repair. Helps process Holliday junction intermediates to mature products by catalyzing branch migration. Has a DNA unwinding activity characteristic of a DNA helicase with a 3'- to 5'- polarity. Unwinds branched duplex DNA (Y- DNA) (By similarity); Belongs to the helicase family. RecG subfamily.
  
    0.701
spoT
Guanosine-3',5'-bis(diphosphate) 3'- pyrophosphohydrolase (spoT); In eubacteria ppGpp (guanosine 3'-diphosphate 5-' diphosphate) is a mediator of the stringent response that coordinates a variety of cellular activities in response to changes in nutritional abundance. This enzyme catalyzes the degradation of ppGpp into GDP. It may also be capable of catalyzing the synthesis of ppGpp (By similarity); Belongs to the RelA/SpoT family.
       0.690
alr
Alanine racemase, biosynthetic (alr); Catalyzes the interconversion of L-alanine and D-alanine. May also act on other amino acids; Belongs to the alanine racemase family.
 
   
 0.678
dapF
Diaminopimelate epimerase (dapF); Catalyzes the stereoinversion of LL-2,6-diaminoheptanedioate (L,L-DAP) to meso-diaminoheptanedioate (meso-DAP), a precursor of L- lysine and an essential component of the bacterial peptidoglycan. Only accepts DAP isomers with the L configuration ; Belongs to the diaminopimelate epimerase family.
     
 0.676
murA
UDP-N-acetylglucosamine 1-carboxyvinyltransferase (murZ); Cell wall formation. Adds enolpyruvyl to UDP-N- acetylglucosamine; Belongs to the EPSP synthase family. MurA subfamily.
