Abstract
THIS communication presents an observation not yet reported concerning the effect of exogenous nicotinamide adenine dinucleotide (NAD) on the activity of uridine diphosphate galactose-4-epimerase. This enzyme (formerly called galactowaldenase) was first demonstrated in yeast extract by Leloir1. NAD was shown later to be required for activity in a calf liver preparation2. The need for an exogenous supply of NAD was further shown in crude human haemolysates3 and in homogenates of L cells4. It now has been found that haemolysates from newborn infants demonstrate a substantial epimerase activity without the addition of NAD.
