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
cqsAAminotransferase, class II; Required for the synthesis of the quorum-sensing autoinducer CAI-1 ((S)-3-hydroxytridecan-4-one) which probably functions as an intragenus signal; Belongs to the class-II pyridoxal-phosphate-dependent aminotransferase family. (389 aa)    
Predicted Functional Partners:
cqsS
Sensor histidine kinase/response regulator LuxN; Senses the quorum-sensing autoinducer CAI-1 ((S)-3- hydroxytridecan-4-one) which probably functions as an intragenus signal. The sensory signal is then relayed to LuxU and LuxO.
 
 
 0.932
bioD
Dethiobiotin synthetase; Catalyzes a mechanistically unusual reaction, the ATP- dependent insertion of CO2 between the N7 and N8 nitrogen atoms of 7,8- diaminopelargonic acid (DAPA) to form an ureido ring.
 
 
 0.893
bioA
Adenosylmethionine-8-amino-7-oxononanoate aminotransferase; Catalyzes the transfer of the alpha-amino group from S- adenosyl-L-methionine (SAM) to 7-keto-8-aminopelargonic acid (KAPA) to form 7,8-diaminopelargonic acid (DAPA). It is the only animotransferase known to utilize SAM as an amino donor; Belongs to the class-III pyridoxal-phosphate-dependent aminotransferase family. BioA subfamily.
 
 
 0.871
tdh
Threonine 3-dehydrogenase; Catalyzes the NAD(+)-dependent oxidation of L-threonine to 2- amino-3-ketobutyrate; Belongs to the zinc-containing alcohol dehydrogenase family.
 
 
 0.871
birA
birA bifunctional protein; Acts both as a biotin--[acetyl-CoA-carboxylase] ligase and a biotin-operon repressor. In the presence of ATP, BirA activates biotin to form the BirA-biotinyl-5'-adenylate (BirA-bio-5'-AMP or holoBirA) complex. HoloBirA can either transfer the biotinyl moiety to the biotin carboxyl carrier protein (BCCP) subunit of acetyl-CoA carboxylase, or bind to the biotin operator site and inhibit transcription of the operon.

VC_1349
Sensory box sensor histidine kinase/response regulator; Similar to PID:1653075; identified by sequence similarity; putative.
  
 
 0.848
VC_2369
Sensor histidine kinase FexB; Similar to SP:P22763 GB:X53315 PID:40951 PID:606149 GB:U00096; identified by sequence similarity; putative.
  
 
 0.848
bioB
Biotin synthase; Catalyzes the conversion of dethiobiotin (DTB) to biotin by the insertion of a sulfur atom into dethiobiotin via a radical-based mechanism; Belongs to the radical SAM superfamily. Biotin synthase family.
 
 
 0.821
VC_1653
Sensory box sensor histidine kinase/response regulator VieS; Similar to GP:3123890; identified by sequence similarity; putative.
  
 
 0.815
VC_2453
