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

ispBOctaprenyl-diphosphate synthase; Polyprenyl synthetase,82% identity to TrEMBL;Q5P1Y1. Has Pfam;PF00348, Polyprenyl synthetase.(IPR000092,Polyprenyl_synt)A variety of isoprenoid compounds are synthesized by various organisms. For example in eukaryotes the isoprenoid biosynthetic pathway is responsible for the synthesis of a variety of end products including cholesterol, dolichol, ubiquinone or coenzyme Q. In bacteria this pathway leads to the synthesis of isopentenyl tRNA, isoprenoid quinones, and sugar carrier lipids. Among the enzymes that participate in that pathway, are a number of [...] (341 aa)    
Predicted Functional Partners:
ispA
Geranyltranstransferase; Geranylgeranyl pyrophosphate synthetase chloroplast precursor (GGPP synthetase) (GGPS) [Includes: Dimethylallyltransferase (EC 2.5.1.1); Geranyltranstransferase (EC 2.5.1.10); Farnesyltranstransferase (EC 2.5.1.29)]. catalyzes the trans-addition of the three molecules of ipp onto dmapp to form geranylgeranyl pyrophosphate. InterPro: Polyprenyl synthetase; High confidence in function and specificity; Belongs to the FPP/GGPP synthase family.
  
  
0.970
uppS
Probable undecaprenyl pyrophosphate synthetase; Catalyzes the condensation of isopentenyl diphosphate (IPP) with allylic pyrophosphates generating different type of terpenoids.
 
 
 0.970
menA
Probable 14-dihydroxy-2-naphthoate octaprenyltransferase (EC 2.5.1.-) (DHNA-octaprenyltransferase). CONVERSION OF 1,4-DIHYDROXY-2-NAPHTHOATE (DHNA) TO DIMETHYLMENAQUINONE (DMK). ATTACHES OCTAPRENYLPYROPHOSPHATE A MEMBRANE-BOUND 40-CARBON SIDE CHAIN TO DHNA. THE CONVERSION OF DHNA TO DMK PROCEEDS IN THREE STAGES: THE REMOVAL OF THE CARBOXYL GROUP OF DHNA AS CO2 THE ATTACHMENT OF THE ISOPRENOID SIDE CHAIN AND A QUINOL-TO-QUINONE OXIDATION WHICH IS THOUGHT TO BE SPONTANEOUS (BY SIMILARITY). TIGRFAM: menA: 14-dihydroxy-2-naphthoate octaprenyltransferase; Specificity unclear.

crtB2
Putative phytoene synthase. Homology to crtB of Synechococcus sp. of 35% (SWISSPROT:CRTB_SYNP7 Is involved in the synthesis of carotenoids. Catalyzes the reaction from prephytoene diphosphate to phytoene. Pfam: Squalene/phytoene synthase no singal peptide no TMHs; Family membership.
  
 0.949
ubiA
4-hydroxybenzoate octaprenyltransferase; Catalyzes the prenylation of para-hydroxybenzoate (PHB) with an all-trans polyprenyl group. Mediates the second step in the final reaction sequence of ubiquinone-8 (UQ-8) biosynthesis, which is the condensation of the polyisoprenoid side chain with PHB, generating the first membrane-bound Q intermediate 3-octaprenyl-4-hydroxybenzoate.
 
 
 0.944
azo0401
Heptaprenyl diphosphate synthase component I, 23% identity (45% similarity) to TrEMBL;Q896H9. Has PF07456,Heptaprenyl diphosphate synthase component I;IPR010898,Hpre_diP_synt_I: This family contains component I of bacterial heptaprenyl diphosphate synthase (approximately 170 residues long). This is one of the two dissociable subunits that form the enzyme, both of which are required for the catalysis of the biosynthesis of the side chain of menaquinone-7.
  
 
 0.909
crtB1
Putative phytoene synthase. Homology to crtB of Synechococcus sp. of 30% (SWISSPROT:CRTB_SYNP7 Is involved in the synthesis of carotenoids. Catalyzes the reaction from prephytoene diphosphate to phytoene. Pfam: Squalene/phytoene synthase no singal peptide no TMHs; Family membership.
