autoinducer inactivation enzyme from Bacillus; hydrolyzes acetyl homoserine lactone

Coding region for the autoinducer inactivation enzyme A (aiiA) LVA tagged (for untagged version see Part:BBa_C0160. The gene was originally isolated from Bacillus sp. 240B1 and it encodes an enzyme that catalyzes the degradation of N-acyl-homoserine lactones (AHLs)--quorum sensing autoinducers.


Usage and Biology

The aiiA gene has 750 nucleotides and encodes a protein of 250aa with a predicted molecular mass of 28,036Da and an isoelectric point of 4.7. The protein has no hydrophobic signal pepetide at the N-terminus and therefore it is believe that it is not secreted. This is supported by the observation that when aiiA is expressed in E.coli DH5alpha or Bacillus 240B1 cells no autoinducer inactivation is detected in the supernatants of these cultures. The AiiA protein has no significant overall homology with other known proteins, but based on the presence of two well-conserved motifs it is believed that it is a metalloenzyme.
