Mutant libraries created by saturation mutagenesis of each single amino acid site D168, A225, K434 and E435 were screened to further improve the capability of cytochrome P450 BM-3(A74G/F87V/L188Q) mutant from Bacillus Megaterium which can hydroxylate indole into indigo. Results showed that D168, K434 and E435 are located at the functional domain of P450 BM-3 protein while A225 is sited at the unfunctional domain.

The oxidase system includes both membrane-bound and soluble cytosolic proteins. The primary feature of this enzyme is stimulus-dependent activation and which mechanism is the phosphorylation and translocation of a complex of cytosolic factors to the membrane, where they associate with a flavocytochrome enzyme.The fully assembled complex functions as an electron transport system,moving electrons from cytosolic NADPH to molecular oxygen to form superoxide anion（O2-）, which, along with subsequent reactive products called respiratory burst,exerts microbicidal and cytotoxic activities.
