explanation, also noted by Hanson and Roses2 If all modern enzymes catalyzing a certain type of reaction evolved from a common ancestral enzyme displaying a particular stereochemicalpreference, a common preference in all modern enzymes might reflect the conservation of the original preference during the evolutionary process. This pair of explanations is merely a molecular example of a ptoblem frequently
