Crystallized Carboxypeptidase, supplied in aqueous toluol suspension is characterized bv its specific effect on the peptide1 linkage adjacent to the carbowl end of the peptide chain.
Acylase, Technical, prepared from pork kidney according to the method of Price, Gilbert, and Greenstein, is useful in the separation of optical isomers of amino acids. [/. Biol Chem. 179, 1169-1174 (1949)]
