title: Molecular cloning of the Pseudomonas putida glyoxalase I gene in Escherichia coli.
abstract: The glyoxalase I gene of Pseudomonas putida was cloned onto a vector plasmid pBR 322 as a 7.5 kilobase Sau 3AI fragment of chromosomal DNA and the hybrid plasmid was designated pGI 318. The gene responsible for the glyoxalase I activity in pGI 318 was recloned in pBR 322 as a 2.2 kilobase Hin dIII fragment and was designated pGI 423. The P. putida glyoxalase I gene on pGI 318 and pGI 423 was highly expressed in E. coli cells and the glyoxalase I activity level was increased more than 150 fold in the pGI 423 bearing strain compared with that of E. coli cells without pGI 423. The E. coli transformants harboring pGI 318 or pGI 423 could grow normally in the presence of methylglyoxal, although the E. coli cells without plasmid were inhibited to grow and showed the extremely elongated cell shape.
