WebHow to calculate the catalytic efficiency (kcat/Km) of an enzyme which has the following values? Enzyme concentration ([E]) used= 20 µg. Molecular weight of enzyme= 43.23 kDa = 389 amino acids x 111 g/mol = 43.23 x 10^3 g/mol = 43230 g/mol. Reaction volume= 100 µl. Km= 38.43 µM. WebDezember 2024. Styrene monooxygenases (SMOs) are two-enzyme systems that catalyze the enantioselective epoxidation of styrene to (S)-styrene oxide. The FADH2 co-substrate of the epoxidase component (StyA) is supplied by an NADH-dependent flavin reductase (StyB). The genome of Rhodococcus opacus 1CP encodes two SMO systems.
