ABSTRACT:
A cysteine proteinase characterized in that it is immunologically distinct, has a molecular mass of about 25,000 and has a distinct net charge is disclosed. "Ananain" and "comosain" are such enzymes, which may be distinguished by their specificities for certain synthetic substrates.
A process for the production thereof is also disclosed which comprises separation from pineapple plant material and purification. Such enzymes may be used in the debridement of eschar tissues.
