ID 1.1.3.49 DE (R)-mandelonitrile oxidase. CA (R)-mandelonitrile + O2 = benzoyl cyanide + H2O2. CC -!- The enzyme, characterized from the millipede Chamberlinius CC hualienensis, is segregated from its substrate, which is contained in CC special sacs. CC -!- The sacs are ruptured during defensive behavior, allowing the enzyme CC and substrate to mix in special reaction chambers leading to CC production of the defensive chemical benzoyl cyanide. //
