Abstract
Membrane spanning regions of 43 kDa and 47 kDa antenna proteins of photosystem II of thylakoid membranes are theoretically predicted. Prediction of topology of chlorophyll-a and beta-carotene molecules in the proteins and interaction of the proteins with 33 kDa extrinsic protein on the lumenal side of thylakoid membrane is based on the findings reported earlier. Each antenna protein is predicted to have six transmembrane alpha-helices with twelve chlorophyll-a and five beta-carotene molecules binding to it. Both N- and C- terminal ends are proposed to be on the stromal side of thylakoid membrane. The proposed structural model conforms to the reported experimental results from the literature.
