Cloning and identification of a phospholipase gene from vibrio mimicus.
The phospholipase gene phl was identified from Vibrio mimicus (ATCC33653) and sequenced. The entire open reading frame (ORF) was composed of 1410 nucleotides and encoding 470 amino acids. The phl was placed upstream of hemolysin gene (vmhA) with opposite direction of transcription. From the BLAST search program, the deduced amino acids sequence showed 74.4% identity with phospholipase gene (lec) from V. cholerae El Tor. The entire ORF of phospholipase gene was amplified by PCR and inserted into an Escherichia coli expression vector, pET22b(+) and introduced E. coli BL21(DE3). SDS-PAGE demonstrated that a protein corresponding to the phospholipase was overexpressed and migrated at a molecular mass of 53 kDa.
