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

uppUracil phosphoribosyltransferase; Catalyzes the conversion of uracil and 5-phospho-alpha-D- ribose 1-diphosphate (PRPP) to UMP and diphosphate. (207 aa)    
Predicted Functional Partners:
pyrF
Rv1385, (MTCY21B4.02), len: 274 aa. Probable pyrF,orotidine 5'-phosphate decarboxylase, identical to DCOP_MYCBO|P42610 Mycobacterium bovis (274 aa). Contains PS00156 Orotidine 5'-phosphate decarboxylase active site. Belongs to the OMP decarboxylase family.
  
 
 0.996
deoA
Probable thymidine phosphorylase DeoA (tdrpase) (pyrimidine phosphorylase); The enzymes which catalyze the reversible phosphorolysis of pyrimidine nucleosides are involved in the degradation of these compounds and in their utilization as carbon and energy sources, or in the rescue of pyrimidine bases for nucleotide synthesis.
 
 
 0.994
pyrR
Probable pyrimidine operon regulatory protein PyrR; Regulates the transcription of the pyrimidine nucleotide (pyr) operon in response to exogenous pyrimidines.
     
 0.989
deoD
Probable purine nucleoside phosphorylase DeoD (inosine phosphorylase) (PNP); The purine nucleoside phosphorylases catalyze the phosphorolytic breakdown of the N-glycosidic bond in the beta- (deoxy)ribonucleoside molecules, with the formation of the corresponding free purine bases and pentose-1-phosphate. Cleaves guanosine, inosine, 2'-deoxyguanosine and 2'-deoxyinosine.
  
 
 0.976
pyrH
Probable uridylate kinase PyrH (UK) (uridine monophosphate kinase) (UMP kinase); Catalyzes the reversible phosphorylation of UMP to UDP.
  
 
 0.962
guaA
Probable GMP synthase [glutamine-hydrolyzing] GuaA (glutamine amidotransferase) (GMP synthetase); Catalyzes the synthesis of GMP from XMP.
  
  
 0.943
rpiB
Ribose-5-phosphate isomerase; Catalyzes the interconversion of ribulose-5-P and ribose-5-P. It has not isomerase activity towards D-allose 6-phosphate.
 
  
 0.920
apt
Adenine phosphoribosyltransferase; Catalyzes a salvage reaction resulting in the formation of AMP, that is energically less costly than de novo synthesis.
  
  
 0.920
cdd
Probable cytidine deaminase Cdd (cytidine aminohydrolase) (cytidine nucleoside deaminase); Recycles cytidine and 2-deoxycytidine for uridine and 2- deoxyuridine synthesis, respectively. Catalyzes the hydrolytic deamination of cytidine and 2-deoxycytidine to form, respectively, uridine and 2-deoxyuridine.

hpt
Rv3624c, (MTCY15C10.28), len: 216 aa. Hpt (alternate gene name: hprT), hypoxanthine-guanine phosphoribosyltransferase (but seems to have a 35 aa extension at N-terminus), equivalent to other mycobacterial hypoxanthine-guanine phosphoribosyltransferases e.g. P96794 from Mycobacterium avium (203 aa), FASTA scores: opt: 1136,E(): 1.2e-65, (88.5% identity in 200 aa overlap); and O69537|HPT|ML0214 from Mycobacterium leprae (213 aa), FASTA scores: opt: 1115, E(): 2.8e-64, (81.6% identity in 212 aa overlap). Also similar to others e.g. Q9X8I5|SCE9.12c from Streptomyces coelicolor (187 aa), FA [...]
