Prediction of the conformation of D1/D2 heterodimer of photosynthetic reaction centre II using a modified Chou-Fasman method.

Chou-Fasman method was modified to account for amphipathic nature of Gly and hydrophobic environment. The modified method shows improvement in prediction accuracy from 35 to 70% and can be applied to predict the conformation of D1, D2 polypeptides of reaction centre II of thylakoid, which are analogous to L and M respectively. Possible sites for Mn binding to D1/D2 heterodimer are postulated.
