Molecular cloning and analysis of a lipase gene from Pseudomonas fluorescens No. 33.
The gene encoding an extracellular lipase from Pseudomonas fluorescens No. 33 was cloned and sequenced. A single open reading frame consisting of 1,428 nucleotides that encoded a mature protein of 476 amino acids was recognized. Sequence analysis showed that the deduced molecular weight of 50,209 agreed with the molecular weight of the purified lipase as measured by SDS-PAGE and the lipase lacked a signal peptide. The presence of a repeating motif, GXXGXDXXX, suggested that the lipase might be exported and secreted via a system that involves the ATP-binding cassette protein.
