Abstract excerpt
The ability of preferredoxin to inactivate a 50-pS anion channel of the chloroplast inner membrane in the presence of an energy source was investigated using single-channel recordings. It was found that preferredoxin cannot inactivate the channel when GTP is the only energy source present. From this it is concluded that the precursor has to interact with the, translocon of the inner membrane of chloroplasts (Tic)...
