STABILIZATION OF CYTOCHROME P450 REDUCTASE

The present invention relates to a recombinant microorganism which is capable of expressing a cytochrome P450 reductase (CPR) and, optionally, a cytochrome P450 enzyme (CYP) and which is capable of overexpressing a Ice2p comprising the amino acid sequence set out in SEQ ID NO: 2 or a sequence having at least 50% sequence identity thereto. The invention further relates to use of Ice2p to stabilize expression of a cytochrome P450 reductase in a recombinant microorganism.
