Factors affecting Proteolytic Activity of Extracts from Normal and Tumour Tissues of Tobacco

Abstract

A SERIES of experiments were undertaken to establish the optimal conditions for extraction of soluble fractions containing proteolytic enzymes from normal and tumour (crown-gall) tissues of Nicotiana tabacum var. Wisconsin, and for assaying the proteolytic activity of these crude stem extracts. It was hoped that the results attained would expedite the selection of a single set of conditions for future extractions of crude plant material for the purpose of purifying the proteolytic principle.
