Activating Compound

Activating Compound Comment Organism Structure
AamD the enzyme requires interaction with the small catalytic coupling/effector protein, substitution of AamD with IsoD, the coupling protein from the closely related isoprene monooxygenase, changes the regioselectivity of toluene hydroxylation and stereoselectivity of styrene epoxidation, although this is accompanied by a high level of uncoupling Xanthobacter autotrophicus

additional information the enzyme contains a Rieske-type ferredoxin. AMO requires a small catalytic coupling/effector protein, AamD, the coupling protein cannot or very poorly be substituted by coupling proteins of AMOs of other species, e.g. IsoD from Rhodococcus sp. strain AD45, or PmoB from Mycobacterium sp. strain M156, substitution with IsoD changes the regioselectivity of toluene hydroxylation and stereoselectivity of styrene epoxidation, although this is accompanied by a high level of uncoupling, overview Xanthobacter autotrophicus
