GONZALEZ-MENDOZA, Daniel. Enzymatic complex cytochrome P450 in plants. Rev. Int. Contam. Ambient [online]. 2007, vol.23, n.4, pp.177-183. ISSN 0188-4999.

Cytochrome P450 dependent enzymes (CYP450) are important in the biosynthesis of many substances and in the detoxification of xenobiotics. In plants, they are involved in the biosynthesis of secondary products (e.g. flavonoids, alkaloids) and hormones, but also in the detoxification of herbicides. On the other hand, the use of molecular techniques, has allowed the insertion of genes of the CYP450 of mammals in a greater number of plants, favoring the tolerance to herbicides. The present contribution is an overview of the biotechnological potentiality of the enzymatic complex CYP450.
