Acid proteases from species of Mucormii. partial characterization of the acid protease produced by a strain of Mucor miehei isolated in Cuba.

The acid protease produced by a strain of Mucor miehei isolated in Cuba was purified by column electrofocusing and partially characterized as to amino-acid composition, molecular weight, helical content, total carbohydrate content, and approximate isoelectric point; A detailed comparison of these results was reported previously for Mucor miehei protease (Ottesen, M. & Rickert, W;S. (1970) C.R. Trav. Labmcarlsberg 37, 301) suggested that the two enzymes are similar but not identicalmthis conclusion was reinforced by an analysis of circular-dichroism spectra.
