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

cpdB2',3'-cyclic-nucleotide 2'-phosphodiesterase (cpdB); This bifunctional enzyme catalyzes two consecutive reactions during ribonucleic acid degradation. Converts a 2',3'-cyclic nucleotide to a 3'-nucleotide and then the 3'-nucleotide to the corresponding nucleoside and phosphate (By similarity). (657 aa)    
Predicted Functional Partners:
HI_0206
5'-nucleotidase, putative; Degrades NAD into adenosine and nicotinamide riboside, the latter being subsequently internalized by a specific permease. Also endowed with NAD(P) pyrophosphatase activity. Exhibits a broad substrate specificity, recognizing either mono- or dinucleotide nicotinamides and different adenosine phosphates with a maximal activity on 5'-adenosine monophosphate; Belongs to the 5'-nucleotidase family.
 
 
 
0.902
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.
    
 0.735
HI_0221.1
Predicted coding region HI0221.1; Brute Force ORF; identified by GeneMark; putative; Belongs to the IMPDH/GMPR family.
    
 0.732
guaA
GMP synthase (guaA); Catalyzes the synthesis of GMP from XMP.
     
 0.724
cca
tRNA nucleotidyltransferase (cca); Catalyzes the addition and repair of the essential 3'- terminal CCA sequence in tRNAs without using a nucleic acid template. Adds these three nucleotides in the order of C, C, and A to the tRNA nucleotide-73, using CTP and ATP as substrates and producing inorganic pyrophosphate. Also shows phosphatase, 2'-nucleotidase and 2',3'-cyclic phosphodiesterase activities. These phosphohydrolase activities are probably involved in the repair of the tRNA 3'-CCA terminus degraded by intracellular RNases.
  
   
 0.681
udk
Uridine kinase (udk); Similar to SP:P31218 GB:X71492 PID:296947 GB:U00096 PID:1736770 percent identity: 67.82; identified by sequence similarity; putative.
  
 
  0.632
cdd
Cytidine deaminase (cdd); This enzyme scavenges exogenous and endogenous cytidine and 2'-deoxycytidine for UMP synthesis.
 
  
  0.620
cpdA
lacZ expression regulator (icc); Hydrolyzes cAMP to 5'-AMP. Plays an important regulatory role in modulating the intracellular concentration of cAMP, thereby influencing cAMP-dependent processes. May coordinate responses to nutritional stress, ensuring optimal competence development. Belongs to the cAMP phosphodiesterase class-III family.
   
 
 0.611
surE
Stationary-phase survival protein (surE); Nucleotidase that shows phosphatase activity on nucleoside 5'-monophosphates; Belongs to the SurE nucleotidase family.
     
 0.581
torZ
Biotin sulfoxide reductase (bisC); Reduces trimethylamine-N-oxide (TMAO) into trimethylamine; an anaerobic reaction coupled to energy-yielding reactions.
