Pseudo-cholinesterase activity in the central nervous system

Abstract

4. An enzyme capable of oxidizing reduced coenzyme I and reducing methylene blue occurred in all types of cell of B. 8UbtiH8 and B. megatherium. 5. Spores of B. megatherium contained a heat- stable substance which inhibited reduction of methylene blue by heart diaphorase, the inhibition being prevented by the addition of large amounts (1 mg.) of coenzyme I.
