title: Chemical structure of angiotensin formed by incubating plasma with the corpuscles of Stannius in the Japanese goosefish, Lophius litulon.
abstract: The chemical structure of angiotensin formed by incubating the extract of the corpuscles of Stannius (CS) with homologous plasma in the Japanese goosefish , Lophius litulon , was analyzed. Goosefish CS angiotensin was proposed as [Asn1, Val5, His9 ] angiotensin I based on amino acid analysis and fluorescent peptide mapping techniques. It had the same structure as angiotensin produced by incubating the kidney extract with homologous plasma, indicating that CS angiotensin was not organ specific.
