Characteristics of hiproly barley II. Quantification of two proteins contributing to its high lysine content

Abstract

Quantitative extraction of salt and water soluble proteins from Hiproly, CI 4362 and Bomi barley was performed and their content of the lysine rich SP II albumin determined by a single radial immunodiffusion assay. The elevated content of SP II albumin in Hiproly accounted for 37% of the difference in crude protein lysine between Hiproly and Bomi and for 19% between Hiproly and its low lysine sisterline CI 4362. Apart from the lysine rich SP II albumin, other proteins contribute to the high lysine content of Hiproly.
