Enzymatic difference between laticifers and cultured cells of papaya

Abstract

Cell suspension cultures of Carica papaya were found to produce a papain-like enzyme showing an amidase activity similar to papain. Experiments suggested that the enzyme was an SH-enzyme, but an immunological test indicated the absence of papain in cultured cells. The isoelectric point (4.3) of the enzyme of cultured cells was the same as that of the leaf extract, but was different from that of papain or other amidases in the latex of the fruit.
