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

DIP1285Conserved hypothetical protein; Similar to Rhizobium loti Mll8746 protein SWALL:Q989X1 (EMBL:AP003008) (280 aa) fasta scores: E(): 3.4e-12, 28.57% id in 210 aa, and to Xylella fastidiosa GMP synthase XF0560 SWALL:Q9PFU7 (EMBL:AE003903) (240 aa) fasta scores: E(): 8.5e-09, 26.97% id in 215 aa. (242 aa)    
Predicted Functional Partners:
guaB
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.
  
 
 0.960
DIP0581
Conserved hypothetical protein; Similar to Corynebacterium ammoniagenes GuaB, ORF genes for IMP dehydrogenase, hypothetical protein TR:Q9RHY9 (EMBL:AB003154) (376 aa) fasta scores: E(): 3.5e-63, 67.18% id in 387 aa, and C-terminal region similar to Escherichia coli inosine-5'-monophosphate dehydrogenase GuaB or GuaR or B2508 or Z3772 or ECS3370 SW:IMDH_ECOLI (P06981) (488 aa) fasta scores: E(): 0.00061, 31.49% id in 181 aa.
  
 
 0.946
apt
Adenine phosphoribosyltransferase; Catalyzes a salvage reaction resulting in the formation of AMP, that is energically less costly than de novo synthesis.
  
 
 0.925
hpt
Similar to Vibrio harveyi hypoxanthine phosphoribosyltransferase Hpt SW:HPRT_VIBHA (P18134) (176 aa) fasta scores: E(): 5.3e-28, 48.21% id in 168 aa, and to Mycobacterium leprae hypoxanthine-guanine phosphoribosyltransferase ML0214 SW:HPRT_MYCLE (O69537) (203 aa) fasta scores: E(): 3.2e-40, 55.31% id in 188 aa; Belongs to the purine/pyrimidine phosphoribosyltransferase family.
  
 
 0.911
gmk
Guanylate kinase; Essential for recycling GMP and indirectly, cGMP.
  
 
 0.910
guaA
GMP synthase [glutamine-hydrolysing]; Catalyzes the synthesis of GMP from XMP.
    
  0.903
DIP1850
Ham1 family 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.
  
 
  0.903
acnR
Putative TetR-famlily transcriptional regulator; AcnR negatively controls the expression of the aconitase gene acn.
       0.789
DIP1286
Conserved hypothetical protein; Similar to Streptococcus pneumoniae ACT domain protein SP0238 SWALL:Q97ST5 (EMBL:AE007336) (88 aa) fasta scores: E(): 4.7e-09, 45.34% id in 86 aa, and to Listeria monocytogenes LMO0533 protein 0533 SWALL:CAC98612 (EMBL:AL591975) (89 aa) fasta scores: E(): 4.8e-09, 40.22% id in 87 aa; Belongs to the UPF0237 family.
       0.695
DIP1287
Similar to Streptococcus pneumoniae hypothetical protein SP0239 SWALL:AAK74419 (EMBL:AE007336) (445 aa) fasta scores: E(): 8e-101, 65.91% id in 446 aa, and to Neisseria meningitidis hypothetical protein NMA1908 SWALL:Q9JTA4 (EMBL:AL162757) (451 aa) fasta scores: E(): 4.7e-98, 62.1% id in 446 aa.
