Secondary structures of the models of BMV 1a. The sequence of the C-terminal fragment of BMV 1a used for model building is aligned with its secondary structure prediction obtained with psi-pred [30] and with the secondary structures obtained by means of DSSP for the SF1 model, SF-2 preliminary and SF2 model (code E is used for β-strand, H for helix and C for coil). Regions forced into helical conformation in the SF-2 model are underlined and hinted in red.
