- beta-cyclopiazonate + acceptor alpha-cyclopiazonate + reduced acceptor
Thus, the two substrates of this enzyme are beta-cyclopiazonate and an acceptor, whereas its two products are alpha-cyclopiazonate and a reduced acceptor.
This enzyme belongs to the family of oxidoreductases, specifically those acting on X-H and Y-H to form an X-Y bond with other acceptors. The systematic name of this enzyme class is beta-cyclopiazonate:acceptor oxidoreductase (cyclizing). Other names in common use include beta-cyclopiazonate oxidocyclase, beta-cyclopiazonic oxidocyclase, and beta-cyclopiazonate:(acceptor) oxidoreductase (cyclizing). It employs one cofactor, FAD.
