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

cypXcyclo-L-leucyl-L-leucyl dipeptide oxidase; Involved in the biosynthesis of pulcherrimin, a red extracellular pigment. Catalyzes the oxidation of cyclo(L-Leu-L-Leu) (cLL) to yield pulcherriminic acid which forms pulcherrimin via a nonenzymic reaction with Fe(3+). Substrates with small alkyl groups (cAA, cLG, cLP) exhibit weaker binding to CYP134A1, but substrates with larger hydrophobic side chains bind in a similar regime to cLL. Belongs to the cytochrome P450 family. (405 aa)    
Predicted Functional Partners:
yvmC
Cyclodipeptide synthase; Involved in the biosynthesis of pulcherrimin, a red extracellular pigment. It uses activated amino acids in the form of aminoacyl-tRNAs (aa-tRNAs) as substrates to catalyze the ATP- independent formation of cyclodipeptides which are intermediates in diketopiperazine (DKP) biosynthetic pathways. Catalyzes the formation of cyclo(L-Leu-L-Leu) (cLL) from L-leucyl-tRNA(Leu). Can also incorporate various nonpolar residues, such as L-phenylalanine, L- leucine and methionine, into cyclodipeptides.

pksJ
Polyketide synthase of type I; Involved in some intermediate steps for the synthesis of the antibiotic polyketide bacillaene which is involved in secondary metabolism.
 
 0.989
dhbF
Siderophore 2,3-dihydroxybenzoate-glycine-threonine trimeric ester bacillibactin synthetase; Specifically adenylates threonine and glycine, and loads them onto their corresponding peptidyl carrier domains.
 
 0.978
srfAC
Surfactin synthetase; Probably activates a leucine.
 
 0.974
pksN
Polyketide synthase of type I; Involved in some intermediate steps for the synthesis of the antibiotic polyketide bacillaene which is involved in secondary metabolism.
 
 0.931
yvmA
Putative efflux transporter; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pt: putative transporter.
   
  
 0.931
yvmB
Putative transcriptional regulator; Represses the expression of the yvmC-cypX operon, which is involved in pulcherriminic acid biosynthesis. Also negatively regulates yvmA, yvnB and its own expression. Positively regulates yisI expression. Acts by binding specifically to a 14-bp palindromic motif, the YvmB box, which is present in the promoter region of the target genes.

yvnA
Putative transcriptional regulator; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pr: putative regulator.
   
  
 0.920
srfAB
Surfactin synthetase; This protein is a multifunctional enzyme able to activate and polymerize the amino acids Leu, Glu, Asp and Val. Activation sites for these AA consist of individual domains.
 
 0.864
ppsE
Plipastatin synthetase; This protein is a multifunctional enzyme, able to activate and polymerize the amino acid Ile as part of the biosynthesis of the lipopeptide antibiotic plipastatin. The activation sites for this amino acid consist of individual domains; Belongs to the ATP-dependent AMP-binding enzyme family.
