Abstract
IN an investigation of the synthesis of nicotinamide adenine dinucleotide (NAD) by Tetrahymena pyriformis we examined the enzyme cleavage of NAD by this ciliate. There seems to be a lack of information about the cleavage of this coenzyme by Protozoa1,2. In preliminary experiments we incubated cell-free homogenates with NAD and saw that its activity, measured with alcohol dehydrogenase, disappeared rapidly, and detailed investigation to identify the enzyme responsible for the cleavage of NAD seemed to be necessary.
