Abstract

The invention relates to highly purified aminopeptidases derived from Streptomycetes which are heat stable. There is further provided assay for the detection and quantitative determination of Neutral Endopeptidase 24.11 and Neutral Proteinase 24.4. A specific aminopeptidase is one derived from Streptomyces griseus, which is a calcium activated metalloprotein.
