Cytochromes P450 constitute a superfamily of haem-thiolate mono-oxygenases that are involved in the oxidative metabolism of lipophilic subtrates. These enzymes require association with cytochrome P450 reductase (CPR) to achieve optimal activities. We have expressed human cytochrome P450 CYP1A1 under the POX2 promoter (pPOX2-CYP1A1) in Y. lipolytica, with or(More)
Since the invention of the PCR technology, adaptation techniques to clone DNA fragments flanking the known sequence continue to be developed. We describe a perfectly annealed cassette available in almost unlimited quantities with variable sticky-and blunt-end restriction enzyme recognition sites for efficient restriction and ligation with the restricted(More)
Positive selection vectors carry genes that upon expression produce proteins that cause host cell deaths. Insertion of foreign DNA fragments within the ORF of the gene disrupts the lethal effect of the expressed protein. This study described the cloning of Family I.4 Bacillus pumilus lipase gene whose expressed protein is toxic and lethal to Escherichia(More)
