Using of Data Base to Determine the Restriction Sites and Drawing Restriction Map for Lipase Gene from Bacillus stearothermophilus

pecific data base was used for restriction enzymes (rebase) and related proteins, to design executive program in quick basic language to determine the restriction sites and drawing restriction map for the complete sequence of lipase gene from Bacillus stearothermophilus. This program which was of a great benefit in prediction of the restriction patterns for the analysis of recombinant DNA molecules was used to determine the restriction sites for 16 enzyme among 46 type of different restriction enzymes having recognition sequences included in lipase gene which they are SmaI, XhoI, SalI, DdeI, ClaI, EagI, BspHI, AccI, EcoRV, HaeII, BanI, BclI, CfrI , SstI, KspI and NaeI. Results showed that it could be determine accurately the restriction sites and fragments sizes resulted in case of the treatment of lipase gene with these restriction endonucleases. It was also enabled to draw restriction map specific for these enzymes and determine coding region for lipase gene sized of 1254 bp included in the complete sequence for the cDNA of the gene sized of 1725 bp.
