Abstract

The presence of the inactive form of the enzyme tyrosinase in the egg of the grasshopper (Melanoplus differentialis) is of considerable interest since it has been found possible to isolate and activate it by various physico-chemical means (Bodine and Carlson, 1940). The reproductibility of these results depends to a great degree upon the purity of the sample of proenzyme obtained. Extensive purification of the enzyme has been carried out and the general physico-chemical properties of various preparations are noted below.
