title: Molecular cloning and nucleotide sequence of the lipase gene from Pseudomonas fragi.
abstract: The gene coding for the lipase of Pseudomonas fragi was cloned into Escherichia coli JM83 by inserting Sau3A-generated DNA fragments into the BamH I site of pUC9. The plasmid isolated, pKKO, was restriction mapped and the position of the lipase gene on the 2.0 kb insert was pinpointed by subcloning. DNA sequencing revealed that the open reading frame comprises 405 nucleotides and gives a preprotein of 135 amino acids with a predicted Mr of 14643. By comparing the putative lipase amino acid sequence with porcine pancreatic, rat lingual and Staphylococcus hyicus lipases the amino acid sequence around the reactive serine was found to be common among the types of lipase which have been reported.
