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.
已发现菠菜的光系统I反应中心含有两条表观分子量约为56,000和64,000的多肽。利用针对玉米PS1A1基因产物的特异性抗体，将56 kDa的多肽鉴定为叶绿体基因PS1A1的产物。据推测，64 kDa的多肽是基因PS1A2的产物。
