The present invention provides novel chymopapain isoenzymes, compositions
thereof, and methods for locally ad-ministering recombinant chymopapain
or synthetic chymopapain to treat a disc disorder. Recombinant
chymopapain or synthetic chymopapain useful in the methods of the
invention can be naturally occurring chymopapain or variant chymopapain,
