Abstrakt: The article presents a study of a bacterial P450-expression system with Escherichia coli. E. coli has no P450 genes its its genome, the organism is a suitable host for characterization of P450. It was transformed with expression vector pET11a carrying a P450 gene and camAB. The expression of P450 in E. coli was also confirmed by their spectral characterization. The UV-visible absorption spectrum of the supernatant of ruptured cell contained the characteristic 390-450 nanometer P450 peak.
