Phenylalanine 87 of Bacillus megaterium cytochrome P450 BM3, a residue close to the heme in the substrate binding pocket, has been replaced by alanine by site-directed mutagenesis. The substitution had no effect on the rate of hydroxylation of laurate and increased the affinity for laurate of both the intact enzyme and its heme domain by 2.6-6-fold in the(More)
Oligonucleotide-directed mutagenesis has been used to replace arginine-47 with glutamate in cytochrome P-450 BM3 from Bacillus megaterium and in its haem domain. The mutant has been characterized by sequencing, mass spectrometry, steady-state kinetics and by optical and NMR measurements of substrate binding. The mutant retains significant catalytic activity(More)
