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

MJ_1646Pyrimidine biosynthesis protein, putative; Similar to GP:340170 percent identity: 31.30; identified by sequence similarity; putative; Belongs to the purine/pyrimidine phosphoribosyltransferase family. (211 aa)    
Predicted Functional Partners:
pyrE
Orotate phosphoribosyl transferase (pyrE); Catalyzes the transfer of a ribosyl phosphate group from 5- phosphoribose 1-diphosphate to orotate, leading to the formation of orotidine monophosphate (OMP).
  
  
 0.924
pyrF
Conserved hypothetical protein; Catalyzes the decarboxylation of orotidine 5'-monophosphate (OMP) to uridine 5'-monophosphate (UMP); Belongs to the OMP decarboxylase family. Type 1 subfamily.
     
 0.913
pyrD
Dihydroorotase dehydrogenase (pyrD); Catalyzes the conversion of dihydroorotate to orotate with NAD(+) as electron acceptor; Belongs to the dihydroorotate dehydrogenase family. Type 1 subfamily.
     
 0.911
pyrK
Cytochrome-c3 hydrogenase, gamma chain; Responsible for channeling the electrons from the oxidation of dihydroorotate from the FMN redox center in the PyrD type B subunit to the ultimate electron acceptor NAD(+).
     
  0.900
purQ
Phosphoribosylformylglycinamidine synthase I, (purQ); Part of the phosphoribosylformylglycinamidine synthase complex involved in the purines biosynthetic pathway. Catalyzes the ATP-dependent conversion of formylglycinamide ribonucleotide (FGAR) and glutamine to yield formylglycinamidine ribonucleotide (FGAM) and glutamate. The FGAM synthase complex is composed of three subunits. PurQ produces an ammonia molecule by converting glutamine to glutamate. PurL transfers the ammonia molecule to FGAR to form FGAM in an ATP- dependent manner. PurS interacts with PurQ and PurL and is thought to [...]
       0.863
prs
Ribose-phosphate pyrophosphokinase, (prsA); Involved in the biosynthesis of the central metabolite phospho-alpha-D-ribosyl-1-pyrophosphate (PRPP) via the transfer of pyrophosphoryl group from ATP to 1-hydroxyl of ribose-5-phosphate (Rib- 5-P). It can also use dATP as diphosphoryl donor.
    
  0.824
hmvA
DNA binding protein; Binds and compact DNA (95 to 150 base pairs) to form nucleosome-like structures that contain positive DNA supercoils. Increases the resistance of DNA to thermal denaturation (in vitro).
       0.810
queE
Coenzyme PQQ synthesis protein III isolog (Haemophilus influenzae}; Catalyzes the complex heterocyclic radical-mediated conversion of 6-carboxy-5,6,7,8-tetrahydropterin (CPH4) to 7-carboxy-7- deazaguanine (CDG), a step common to the biosynthetic pathways of all 7-deazapurine-containing compounds.
       0.703
MJ_1644
Hypothetical protein; Identified by GeneMark; putative; M. jannaschii predicted coding region MJ1644.
       0.657
MJ_0558
Conserved hypothetical protein; Similar to GB:AE000666 percent identity: 41.96; identified by sequence similarity; putative.
