Cathepsin D activity in isolated odontoblasts.
The presence of an acid proteinase with a high activity has been demonstrated in isolated odontoblast-predentine material from dentinogenically active rat incisors. The enzyme was identified as cathepsin D (EC 3.4.23.5). The possible significance of the enzymatic degradation of proteoglycans and glycosaminoglycans in the course of the calcification process is discussed.
