The controversy in Britain in 1986 over changing the language of "Baa Baa Black Sheep" because, it was alleged in the popular press, it was seen as racially dubious, was apparently based only on a rewriting of the rhyme in one
(S)-canadine synthase (S)-canadine synthase In enzymology, a (S)-canadine synthase () is an enzyme that catalyzes the chemical reaction The 4 substrates of this enzyme are (S)-tetrahydrocolumbamine, NADPH, H, and O, whereas its 3 products are (S)-canadine, NADP, and HO. This enzyme belongs to the family of oxidoreductases, specifically those acting on paired donors, with O as oxidant and incorporation or reduction of oxygen. The oxygen incorporated need not be derived from O with NADH or NADPH as one donor, and the other dehydrogenated. The systematic name of this enzyme class is (S)-tetrahydrocolumbamine,NADPH:oxygen oxidoreductase (methylenedioxy-bridge-forming). Other names in common use include (S)-tetrahydroberberine synthase,
