Abstract

Microsomes isolated from Spodoptera frugiperda (Sf)9 cells infected wi th human FM01 recombinant baculovirus catalyzed the NADPH- and 02-dependent oxidation of methimazole, thiourea, and phenylthiourea. However there was no detectable activity with 1,3-diphenylthiourea or larger thiocarbamides. Microsomes from control Sf9 cells were devoid of methimazole or thiourea S-oxygenase activity. (omitted)
