Cellulase from leaves and roots of tobacco

Abstract

An enzyme that can depolymerize Na carboxymethylcellulose, and split reprecipitated cellulose was found in tobacco plants. The enzyme, which is similar in properties to animal and fungal cellulases, is present in very low concns. It is suggested that this may be explained by its localization in cells in which reconstruction of the thin primary cell wall is occurring as a concomitant of cell growth.
