Construction of photosynthetic antenna complex using light-harvesting polypeptide-α from photosynthetic bacteria, R. rubrum with zinc substituted bacteriochlorophyll α

The light-harvesting (LH)-alpha polypeptide isolated from R. rubrum only organized zinc bacteriochlorophyll a (Zn-BChl a) complex in n-octyl-beta-D-glucopyranoside (OG) micelle, analogous to the LH1-type complex of photosynthetic bacteria.
