the specificity of action of bovine brain cortex cathepsin d ( ec 3.4.23.5 ) and high-mr aspartic endopeptidase ( ec 3.4.23.- ) was studied with the vasoactive peptides renin substrate tetradecapeptide ( rstp ) , substance p ( sp ) , and angiotensins i and ii , and with model peptides -- lys-pro-ala-glu-phe-phe ( no2 ) -ala-leu ( i ) , gly-gly-his-phe ( no2 ) -phe-ala-leu-nh2 ( ii ) , and abz-ala-ala-phe-phe-pna ( iii ) .
