title: Identification of polypeptides of photosystem I reaction center as the products of chloroplast genes PS1A1 and PS1A2.
abstract: The Photosystem I Reaction Center of spinach was found to contain two polypeptides of approximate apparent Mr of 56,000 and 64,000. the 56 kDa polypeptide was identified as the product of chloroplast gene PS1A1 using an antibody specific for the PS1A1 gene product of corn. Presumably the 64 kDa polypeptide is the product of gene PS1A2.
