title: Chemical structure of angiotensin in the turtle, Pseudemys scripta.
abstract: The chemical structure of angiotensin generated by incubating kidney extract with homologous plasma from the turtle, Pseudemys scripta, has been analyzed. The turtle angiotensin was proposed to be [Asp1, Val5, His9] ANG I by its amino acid composition and by its fluorescent peptide mapping. It was the same structure as angiotensin I in the ox and the sheep. The N-terminal amino acid of the turtle angiotensin was not blocked, unlike that of another reptilian angiotensin found in the snake, Elaphe climacophora.
