1 A recombinant CYP11B1 dependent Escherichia coli biocatalyst for selective cortisol production and optimization towards a preparative scale. Hydrocortisone cytochrome P450 family 11 subfamily B member 1 Homo sapiens
2 CYP11B1 thus offers a great potential for biotechnological application in large-scale synthesis of cortisol. Hydrocortisone cytochrome P450 family 11 subfamily B member 1 Homo sapiens
3 For the subsequent optimization of the whole-cell activity 3 different approaches were pursued: Firstly, CYP11B1 expression was enhanced 3.3-fold to 257 nmol*L(-1) by site-directed mutagenesis of position 23 from glycine to arginine, which was accompanied by a 2.6-fold increase in cortisol yield. Hydrocortisone cytochrome P450 family 11 subfamily B member 1 Homo sapiens
