The biosynthesis of membrane proteins in maize plastids at different stages of differentiation of the chloroplast lamellar system was studied. Prolamellar and lamellar system preparations were isolated from maize plastids, disintegrated by osmotic shock under hypotonic conditions. Changes in the amino acid composition of 14C membrane proteins were observed at all stages of chloroplast ultrastructure formation. The maximal level of the apolar amino acids was observed in the membrane fraction of chloroplasts. Washed membranes from maize proplastids and chloroplasts can be resolved into at least 14 protein bands on formic acid--urea polyacrylamide gel. It is pointed out that biogenesis process leads to the increase of lipophylic protein content in the chloroplast lamellae fraction. |
