The newly reported 9-kDa polypeptide in photosystem I [(1991) FEBS Lett. 280, 332-334] is an extrinsic component located on the lumenal side of the thylakoid membrane. This subunit can be solubilized with high salt buffer and does not bind any cofactors. The photosystem I electron transfer chain remains intact and functional in the absence of this component as characterized by the photoreduction of NADP+.
光系统I中新报道的9-kDa多肽[(1991)《欧洲生物化学学会联合会快报》280, 332 - 334]是一种位于类囊体膜腔侧的外在成分。该亚基可用高盐缓冲液溶解,且不结合任何辅因子。如以NADP + 的光还原为特征所示,在没有该成分的情况下,光系统I电子传递链仍保持完整并具有功能。
