STUDIES ON THE CHANGES OF TOBACCO MEMBRANE PROTEIN SECONDARY CONFORMATION AFTER INFECTED WITH TMV

The changes of secondary conformations of tobacco cell membrane protein after TMV-infection was investigated by CD Spectra Technique and the changes in membrane molecular conformations was checked. The results showed that the α-helix decreased and β-turn increased in membrane protein conformations after TMV-infection. In infected tobacco, the α-helix of the cell membrane protein secondary conformations increased and β-turn decreased after acetylshikonin treatment.
