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

pepPXaa-Pro aminopeptidase I; Release of any N-terminal amino acid, including proline, that is linked to proline, even from a dipeptide or tripeptide. Binds 2 manganese ions per subunit.Belongs to the peptidase M24B family. (481 aa)    
Predicted Functional Partners:
nifJ1
Oxidoreductase required for the transfer of electrons from pyruvate to flavodoxin, which reduces nitrogenase, Pyruvate + CoA + oxidized flavodoxin = acetyl-CoA + CO2 + reduced flavodoxin.
  
  
 0.557
nifJ2
Pyruvate:ferredoxin (Flavodoxin) oxidoreductase.
  
  
 0.554
CBL57106.1
5.2 Protein of unknown function similar to proteins from other organisms.
       0.554
pepN
Aminopeptidase with broad substrate specificity. Preference for leucine, cleaves also next to Arg and lysine. Release of an N-terminal aa, Xaa-|-Yaa-. Xaa is preferably Ala. Xaa-Pro may be released. Peptidase M1 family. Monomer. Binds 1 zinc ion per subunit, Cytoplasmic.

guaB2
Inosine-5-monophosphate dehydrogenase (IMP dehydrogenase) (IMPDH) (IMPD) / GMP reductase.
 
 
   0.503
guaB1
Inosine-5-monophosphate dehydrogenase (IMP dehydrogenase) (IMPDH) (IMPD) / GMP reductase); Catalyzes the conversion of inosine 5'-phosphate (IMP) to xanthosine 5'-phosphate (XMP), the first committed and rate-limiting step in the de novo synthesis of guanine nucleotides, and therefore plays an important role in the regulation of cell growth. Belongs to the IMPDH/GMPR family.
