Purification of human renin by affinity chromatography using a new peptide inhibitor of renin, H.77 (D-His-Pro-Phe-His-LeuR-Leu-Val-Tyr)

G D McIntyre et al. Biochem J. .

Abstract

A new affinity column for renin was prepared by coupling the isosteric peptide inhibitor of renin, H.77 (D-His-Pro-Phe-His-LeuR-Leu-Val-Tyr, where R is a reduced isosteric bond, -CH2-NH-), to activated 6-aminohexanoic acid-Sepharose 4B. Chromatography of a crude extract of human kidney cortex on this material resulted in a 5500-fold purification of renin in 76% yield. The purified enzyme (specific activity 871 units/mg) was free of non-specific acid-proteinase activity and was stable at pH 6.8 and -20 degrees C over a period of several weeks.
