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 supplies octaprenyl diphosphate, the precursor for the side chain of the isoprenoid quinones, ubiquinone and menaquinone; Localized in the cytoplasm; High confidence in function and specificity. (325 aa)    
Predicted Functional Partners:
uppS
Undecaprenyl pyrophosphate synthetase; Catalyzes the condensation of isopentenyl diphosphate (IPP) with allylic pyrophosphates generating different type of terpenoids.
 
 
 0.964
idsA
Bifunctional short chain isoprenyl diphosphate synthase; IdsA is a bifunctional enzyme with dimethylallyltranstransferase and geranyltranstransferase activities. It is a key enzyme in isoprenoid biosynthesis which supplies sesquiterpene precursors for several classes of essential metabolites including sterols, dolichols, ubiquinones and carotenoids as well as substrates for farnesylation and geranylgeranylation of proteins. The enzyme is a homodimer of subunits, typically having two aspartate-rich motifs with two sets of substrate binding sites for an allylic diphosphate and isopenteny [...]

crtB
The phytoene synthetase (PSY) catalyzes the conversion of two molecules of geranylgeranyl diphosphate (GGPP) into phytoene. It is the second step in the biosynthesis of carotenoids from isopentenyl diphosphate. The reaction carried out by PSY is catalyzed in two separate steps: the first is a head-to-head condensation of the two molecules of GGPP to form prephytoene diphosphate, this intermediate is then rearranged to form phytoene; Belongs to the phytoene/squalene synthetase family; Localized in the cytoplasm; High confidence in function and specificity.
  
 0.915
CAZ95297.1
Prenyltransferase family protein; Multi-pass membrane protein that contains eight transmembrane segments; Localized in the cytoplasmic membrane; Family membership.
 
 
 0.858
menA
1,4-dihydroxy-2-naphthoate octaprenyltransferase; Conversion of 1,4-dihydroxy-2-naphthoate (DHNA) to demethylmenaquinone (DMK); Belongs to the MenA family. Type 1 subfamily.
    
 0.835
ndkA
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.
 
 
 0.650
hemCD
Porphobilinogen deaminase / Uroporphyrinogen-III synthase; Tetrapolymerization of the monopyrrole PBG into the hydroxymethylbilane pre-uroporphyrinogen in several discrete steps. Belongs to the HMBS family.
 
  
 0.577
rlmN
Radical SAM family protein; Specifically methylates position 2 of adenine 2503 in 23S rRNA and position 2 of adenine 37 in tRNAs; Belongs to the radical SAM superfamily. RlmN family.
       0.566
queA
S-adenosylmethionine:tRNA ribosyltransferase-isomerase; Transfers and isomerizes the ribose moiety from AdoMet to the 7-aminomethyl group of 7-deazaguanine (preQ1-tRNA) to give epoxyqueuosine (oQ-tRNA).
  
  
 0.531
rpsE
Ribosomal protein S5; Located at the back of the 30S subunit body where it stabilizes the conformation of the head with respect to the body. Belongs to the universal ribosomal protein uS5 family.
