Comparative Studies on Angiotensins. VI. Structure of Angiotensin I produced by Renal Renin of the Dog, Guinea Pig and Rabbit, and Re-examination of the Peptides of the Pig, Horse and Ox using Homologous Renin Sources

Abstract

Native angiotensins of dog, guinea pig, rabbit, horse, pig and ox were isolated from plasma using homologous kidney extract as the renin source, and their sequences were analyzed by means of amino acid analysis and fluorescent peptide mapping. Angiotensins of dog, guinea pig and rabbit were identical with Ile⁵-angiotensin I, and the sequences of native angiotensins of the other species were in accord with the results reported previously.
