摘要
The polypeptides of the trimeric seed storage protein phaseolin comprise two structurally similar units each made up of a β-barrel and an α-helical domain. The β-barrel has the 'jelly-roll' folding topology of the viral coat proteins and the α-helical domain shows structural similarity to the helix - turn - helix motif found in certain DNA-binding proteins.
