The invention discloses a DNA for high-level expression of N-acyl homoserine lactonase in yeasts and engineering bacteria constructed thereby. The DNA provided by the invention is the DNA expressed by the sequence 2 in a sequence list. On the basis of the traditional homoserine lactonase gene aiiaB546, the DNA sequence thereof is optimized to obtain the optimized gene aiiaB546 M by the method. The expression ability of the optimized gene in Pichia pastoris is obviously higher than that of the gene before optimization. An aiiaB546 M-containing recombinant expression plasmid is constructed; and recombination strains of the high-efficient homoserine lactonase can be obtained by introducing the recombinant expression plasmid into the Pichia pastoris. The expression ability of one of the recombination strains is particularly high. The DNA and the engineering bacteria have great value to the production of the homoserine lactonase.
