Abstract :
Azorhizobium caulinodans is a nitrogen-fixing bacterium that forms stem and root nodules on Sesbania rostrata. All tested A. caulinodans strains exhibited degradation activity against the quorum-sensing signaling compounds, N-acyl-l-homoserine lactones (AHL). The AHL-degrading gene homolog, attM, was identified in the genome sequences of A. caulinodans MAFF 210031(T) and other A. caulinodans strains. Recombinant AttM functions as an AHL lactonase that hydrolyzes the lactone bond of AHL and retains its stable activity at environmental temperatures. The AHL-degrading activity of the attM-deletion mutant was completely diminished, which revealed that AHL degradation by MAFF 210031 was dependent on attM. |
