Solubilization and properties of chloroplast lamellar protein.

Abstract
Most of the protein of chard and corn chloroplast lamellae and corn proplastids was solubilized by treatment with n-butanol at room temperature. No detergent was required to solubilize the proteins. The solubilized proteins interacted with large amounts of chloroplast lipid and chlorophyll, and tests with the chard protein showed that the protein could also interact with phospholipid and cyto-chrome. The amino acid compositions of all the proteins were remarkably similar.
