STRINGSTRING
pqqE protein (Maritimibacter alkaliphilus) - STRING interaction network
"pqqE" - Pyrroloquinoline quinone biosynthesis protein E in Maritimibacter alkaliphilus
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:
some 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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

pqqEPyrroloquinoline quinone biosynthesis protein E (383 aa)    
Predicted Functional Partners:
pqqC
Pyrroloquinoline quinone biosynthesis protein C ; Ring cyclization and eight-electron oxidation of 3a-(2- amino-2-carboxyethyl)-4,5-dioxo-4,5,6,7,8,9-hexahydroquinoline- 7,9-dicarboxylic-acid to PQQ (235 aa)
 
   
  0.995

RB2654_12999
Uroporphyrin-III C-methyltransferase-like ; Multifunctional enzyme that catalyzes the SAM-dependent methylations of uroporphyrinogen III at position C-2 and C-7 to form precorrin-2 via precorrin-1. Then it catalyzes the NAD- dependent ring dehydrogenation of precorrin-2 to yield sirohydrochlorin. Finally, it catalyzes the ferrochelation of sirohydrochlorin to yield siroheme (476 aa)
   
   
  0.715
pqqA
Pyrroloquinoline quinone biosynthesis protein A ; Required for coenzyme pyrroloquinoline quinone (PQQ) biosynthesis. PQQ is probably formed by cross-linking a specific glutamate to a specific tyrosine residue and excising these residues from the peptide (26 aa)
              0.666
RB2654_21153
Transport permease protein (269 aa)
 
          0.655
