Different types of homologous enzyme pairs at minimal path length (MPL) 1. a) Enzymes that catalyze similar reactions. The enzymes are at MPL 1 because they both catalyse reactions involving the metabolite fructose-1,6-bisphosphate. b) Enzymes that catalyze reactions that are mechanistically different. These enzymes are at MPL 1 because they both catalyse reactions involving chorismate.
