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

guaAPutative GMP synthase; Catalyzes the synthesis of GMP from XMP. (529 aa)    
Predicted Functional Partners:
guaB2
Putative inosine-5'-monophosphate dehydrogenase; 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.

guaB1
Inosine-5'-monophosphate dehydrogenase; Previously sequenced as TR:O32912 (EMBL:AL008609) fasta scores: E(): 0, 100.0% in 478 aa. Similar to Mycobacterium tuberculosis inosine-5'-monophosphate dehydrogenase rv1843c SW:YI43_MYCTU (Q50591) fasta scores: E(): 0, 86.4% in 478 aa, and to Bacillus subtilis inosine-5'-monophosphate dehydrogenase SW:IMDH_BACSU (P21879) fasta scores: E(): 0, 37.7% in 472 aa. Contains 2 Pfam matches to entry PF00571 CBS, CBS domain. Contains Pfam match to entry PF00478 IMPDH_C, IMP dehydrogenase / GMP reductase C terminus. Contains Pfam match to entry PF01574 IM [...]

guaB3
Similar to M. tuberculosis guaB3, Rv3410c, putative inosine-5'-monophosphate dehydrogenase, SW:YY10_MYCTU (Q50716) (375 aa); Fasta score E(): 0, 90.5% identity in 368 aa overlap. This ORF is similar in part to ML0387 and ML2066, which more closely resemble the experimentally characterised IMP-DH's (e.g. from Escherichia coli). This shorter homologue is conserved in several bacterial genera. Previously sequenced as SW:YY10_MYCLE (U00015) (375 aa); Fasta score E(): 0, 100.0% identity in 370 aa overlap. Contains Pfam match to entry PF00478 IMPDH_C, IMP dehydrogenase / GMP reductase C term [...]

gmk
Putative guanylate kinase; Essential for recycling GMP and indirectly, cGMP.
  
 
 0.970
pheT
phenylalanyl-tRNA synthase [beta] subunit; Highly similar to many phenylalanyl-tRNA synthetase beta chains including: Escherichia coli SW:SYFB_ECOLI (P07395) (795 aa); Fasta score E(): 0, 31.0% identity in 851 aa overlap and Mycobacterium tuberculosis RV1649 SW:SYFB_MYCTU (P94985) (831 aa); Fasta score E(): 0, 79.6% identity in 834 aa overlap.
  
  
 0.967
pyrG
CTP synthase; Catalyzes the ATP-dependent amination of UTP to CTP with either L-glutamine or ammonia as the source of nitrogen. Regulates intracellular CTP levels through interactions with the four ribonucleotide triphosphates.
  
 
 0.965
hpt
Putative hypoxanthine phosphoribosyltransferase; Similar to M. tuberculosis hpt, Rv3624c, probable hypoxanthine-guanine phosphoribosyltransferase, SW:HPRT_MYCTU (O06383) (216 aa); Fasta score E(): 0, 83.1% identity in 207 aa overlap. Similar to many e.g. Salmonella typhimurium hprt, hypoxanthine phosphoribosyltransferase, TR:O33799 (EMBL:AF008931) (178 aa); Fasta score E(): 9.6e-32, 50.9% identity in 169 aa overlap. Previously sequenced as TR:O69537 (EMBL:AL023093) (213 aa); Fasta score E(): 0, 99.5% identity in 213 aa overlap. Contains Pfam match to entry PF00156 Pribosyltran, Phospho [...]

ML1175
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.

tuf
Elongation factor EF-Tu; This protein promotes the GTP-dependent binding of aminoacyl- tRNA to the A-site of ribosomes during protein biosynthesis.

argS
arginyl-tRNA synthase; Identical to the previously sequenced Mycobacterium leprae arginyl-tRNA synthetase (EC 6.1.1.19) (arginine--tRNA ligase) SW:SYR_MYCLE (P45840) (550 aa); Fasta score E(): 0, 99.6% identity in 550 aa overlap. Also highly similar to many other arginyl-tRNA synthetases including: Mycobacterium tuberculosis SW:SYR_MYCTU (Q10609) (550 aa); Fasta score E(): 0, 84.9% identity in 550 aa overlap and Brevibacterium lactofermentum SW:SYR_BRELA (P41253) (550 aa); Fasta score E(): 0, 63.8% identity in 550 aa overlap.
