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

Ppha_2249Non-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. (234 aa)    
Predicted Functional Partners:
guaA
GMP synthase, large subunit; Catalyzes the synthesis of GMP from XMP.
 
 
 0.968
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.
  
 0.936
ndk
Nucleoside-diphosphate kinase; Major role in the synthesis of nucleoside triphosphates other than ATP. The ATP gamma phosphate is transferred to the NDP beta phosphate via a ping-pong mechanism, using a phosphorylated active-site intermediate; Belongs to the NDK family.
  
 0.930
murI
Glutamate racemase; Provides the (R)-glutamate required for cell wall biosynthesis.
 
    0.910
Ppha_1762
PFAM: glutamine amidotransferase class-I; KEGG: cph:Cpha266_0839 glutamine amidotransferase.
  
 
 0.905
Ppha_2780
TIGRFAM: MazG family protein; PFAM: MazG nucleotide pyrophosphohydrolase; KEGG: cph:Cpha266_0151 nucleoside triphosphate pyrophosphohydrolase.
    
  0.903
surE
Stationary-phase survival protein SurE; Nucleotidase that shows phosphatase activity on nucleoside 5'-monophosphates; Belongs to the SurE nucleotidase family.
    
 0.901
uppP
Undecaprenol kinase; Catalyzes the dephosphorylation of undecaprenyl diphosphate (UPP). Confers resistance to bacitracin; Belongs to the UppP family.
 
   
 0.841
pdxJ
Pyridoxal phosphate biosynthetic protein PdxJ; Catalyzes the complicated ring closure reaction between the two acyclic compounds 1-deoxy-D-xylulose-5-phosphate (DXP) and 3-amino- 2-oxopropyl phosphate (1-amino-acetone-3-phosphate or AAP) to form pyridoxine 5'-phosphate (PNP) and inorganic phosphate.
   
   0.811
Ppha_0928
Sun protein; Specifically methylates the cytosine at position 967 (m5C967) of 16S rRNA.
  
  
 0.560
