autoinducer inactivation enzyme from Bacillus; hydrolyzes acetyl homoserine lactone
Coding region for the autoinducer inactivation enzyme A (aiiA) LVA tagged. 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 <em>aiiA </em>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 <em>N</em>-terminus and therefore it is believe that it is not secreted. This is supported by the observation that when <em>aiiA </em>is expressed in <em>E.coli</em> DH5alpha or <em>Bacillus</em> 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.
