Mushroom tyrosinase, which is known to catalyse the conversion of o-diphenols into o-benzoquinones, has been shown to catalyse the oxidative decarboxylation of 3,4-dihydroxymandelic acid [Sugumaran (1986) Biochemistry 25, 4489-4492]. To account for t

The mechanism of oxidation of 1,2-dehydro-N-acetyldopamine (dehydro NADA) was examined to resolve the controversy between our group and Andersen's group regarding the reactive species involved in beta-sclerotization. While Andersen has indicated that

Mushroom tyrosinase, which is known to convert a variety of o-diphenols into o-benzoquinones, has been shown to catalyse an unusual oxidative decarboxylation of 3,4-dihydroxymandelic acid to 3,4-dihydroxybenzaldehyde [Sugumaran (1986) Biochemistry 25

The oxidation of 3,4-dihydroxybenzyl alcohol, one of the sclerotizing precursors for the tanning of the ootheca of cockroach Periplaneta americana, is reported for the first time. Mushroom tyrosinase catalyzed oxidation of 3,4-dihydroxybenzyl alcohol

Proteins solubilized from the pharate cuticle of Manduca sexta were fractionated by ammonium sulfate precipitation and activated by the endogenous enzymes. The activated fraction readily converted exogenously supplied N-acetyldopamine (NADA) to N-ace

The metabolism of N-beta-alanyldopamine (NBAD) by Sarcophaga bullata was investigated. Incubation of NBAD with larval cuticular preparations resulted in the covalent bindings of NBAD to the cuticle and generation of N-beta-alanyl-norepinephrine (NBAN

The mode of oxidation of 1,2-dehydro-N-acetyldopamine by nonenzymatic and enzymatic systems was examined. At acidic and near neutral pH, this compound is fairly stable; however, even at slightly alkaline pH it is highly labile and undergoes spontaneo

Tyrosinase, which usually catalyzes the conversion of o-diphenols to o-benzoquinones, catalyzed an unusual oxidative dimerization of 1,2-dehydro-N-acetyl-dopamine to a benzodioxan derivative. The identity of the product was confirmed by UV, IR spectr
