Abstract
The object of the present invention is to find and produce cathepsin L having high activity under neutral to alkaline conditions and at a low temperature range. The present inventors succeeded in discovering novel cathepsin L having activity even at a low temperature range from hepatopancreas of Japanese northern shrimp. The present inventors further determined the gene sequence encoding said novel cathepsin L, thus enabling production thereof by genetic recombination.
