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.

pqqACoenzyme PQQ synthesis 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 (By similarity); Belongs to the PqqA family. (23 aa)    
Predicted Functional Partners:
PP_2267
Putative Phage single-stranded DNA-binding protein; Function proposed based on presence of conserved amino acid motif, structural feature or limited homology.
      
 0.867
PP_2269
Putative N-acetylmuramoyl-L-alanine amidase; Function proposed based on presence of conserved amino acid motif, structural feature or limited homology.
      
 0.867
yadG
Putative ABC transporter - ATP binding subunit; Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative transporter; Transport and binding proteins.
      
 0.819
agmR
Glycerol metabolism activator.
      
 0.789
gbdR
AraC-family transcriptional regulator; Function experimentally demonstrated in the studied genus; regulator; Regulatory functions.
      
 0.766
gstB
Glutathione S-transferase reducing arsenate to arsenite; Function of homologous gene experimentally demonstrated in an other organism; enzyme; Unknownfunction : Enzymes of unknown specificity.
      
 0.764
pqqB
Coenzyme PQQ synthesis protein B; May be involved in the transport of PQQ or its precursor to the periplasm; Belongs to the PqqB family.
       0.559
pqqF
Coenzyme PQQ synthesis protein F; Required for coenzyme pyrroloquinoline quinone (PQQ) biosynthesis. It is thought that this protein is a protease that cleaves peptides bond in a small peptide (gene pqqA), providing the glutamate and tyrosine residues which are necessary for the synthesis of PQQ (By similarity).
