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; Provides the (R)-glutamate required for cell wall biosynthesis. (292 aa)    
Predicted Functional Partners:
murD
UDP-N-acetylmuramoylalanine--D-glutamate ligase; Cell wall formation. Catalyzes the addition of glutamate to the nucleotide precursor UDP-N-acetylmuramoyl-L-alanine (UMA). Belongs to the MurCDEF family.

AFZ48325.1
Non-canonical purine NTP pyrophosphatase, rdgB/HAM1 family; 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.

purQ
Phosphoribosylformylglycinamidine synthase subunit 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 PurL and is thought to [...]

murC
UDP-N-acetylmuramate--L-alanine ligase; Cell wall formation; Belongs to the MurCDEF family.
 
   
 0.637
murG
Undecaprenyl-PP-MurNAc-pentapeptide-UDPGlcNAc GlcNAc transferase; 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); Belongs to the glycosyltransferase 28 family. MurG subfamily.

AFZ46585.1
Glutamate synthase (NADH) large subunit; PFAM: Conserved region in glutamate synthase; GXGXG motif; Glutamate synthase central domain; Glutamine amidotransferases class-II; COGs: COG0069 Glutamate synthase domain 2; InterProIPR000583:IPR006982:IPR002932:IPR002489:IPR 017932; KEGG: cyc:PCC7424_3654 glutamate synthase (ferredoxin); PFAM: glutamine amidotransferase class-II; glutamate synthase; ferredoxin-dependent glutamate synthase; glutamate synthase alpha subunit domain protein; PRIAM: Glutamate synthase (ferredoxin); SPTR: Glutamate synthase (Ferredoxin).

AFZ46002.1
Alanine racemase; Catalyzes the interconversion of L-alanine and D-alanine. May also act on other amino acids; Belongs to the alanine racemase family.

topA
DNA topoisomerase I; 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 DNA supe [...]
