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

Score
pcpPyrrolidone-carboxylate peptidase; Removes 5-oxoproline from various penultimate amino acid residues except L-proline; Belongs to the peptidase C15 family. (215 aa)    
Predicted Functional Partners:
coaE
Dephosphocoenzyme A kinase; Catalyzes the phosphorylation of the 3'-hydroxyl group of dephosphocoenzyme A to form coenzyme A; Belongs to the CoaE family.
      0.807
folN
5-formyltetrahydrofolate cyclo-ligase; Evidence 2a: Function of homologous gene experimentally demonstrated in an other organism; Product type e: enzyme; Belongs to the 5-formyltetrahydrofolate cyclo-ligase family.
   
  
 0.800
ycsF
Putative nitrogen-containing heterocycle degradation enzyme; Catalyzes the cleavage of 5-oxoproline to form L-glutamate coupled to the hydrolysis of ATP to ADP and inorganic phosphate. Belongs to the LamB/PxpA family.
  
  
 0.764
kipA
Putative hydrolase subunit antagonist of KipI; Catalyzes the cleavage of 5-oxoproline to form L-glutamate coupled to the hydrolysis of ATP to ADP and inorganic phosphate. In addition, counteracts the inhibitory action of PxpB (KipI) on sporulation, by binding to PxpB and preventing its function as an inhibitor of kinase A.
  
  
 0.645
kipI
Putative inhibitor of the autophosphorylation reaction of KinA; Catalyzes the cleavage of 5-oxoproline to form L-glutamate coupled to the hydrolysis of ATP to ADP and inorganic phosphate. In addition, is a potent inhibitor of the autophosphorylation reaction of kinase A (kinA) and its reverse reaction, but does not inhibit phosphate transfer to the Spo0F response regulator once kinase A is phosphorylated. Is an inhibitor of the catalytic domain of kinase A affecting the ATP/ADP reactions and not the phosphotransferase functions of this domain. The inhibition is non- competitive with re [...]

ycbU
Putative cysteine desulfurase; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pe: putative enzyme.
  
    0.559
yuxL
Putative acylaminoacyl-peptidase; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative enzyme; Belongs to the peptidase S9C family.
 
    0.517
moaC
Molybdenum cofactor biosynthesis protein C; Catalyzes the conversion of (8S)-3',8-cyclo-7,8- dihydroguanosine 5'-triphosphate to cyclic pyranopterin monophosphate (cPMP); Belongs to the MoaC family.
      
 0.508
rex
Transcription repressor of cydABCD and yjlC-ndh expression; Modulates transcription in response to changes in cellular NADH/NAD(+) redox state.
      
 0.491
ycsI
Conserved hypothetical protein; Evidence 4: Homologs of previously reported genes of unknown function; PubMedId: 9334321; Belongs to the D-glutamate cyclase family.
