1.14.99.14 | gene CYP509C12, cloning from a cDNA library, DNA and amino acid sequence determination and analysis, phylogenetic analysis, and recombinant expression in Pichia pastoris, coexpression with NAD(P)H-dependent reductase also from Rhizopus oryzae, which improves electron transfer to CYP509C12 and thus increases the production of 11-hydroxyprogesterone by 7fold. The engineered strain displays total bioconversion of progesterone into 11alpha-hydroxyprogesterone and small amounts of 6beta-hydroxyprogesterone |
