The 21 kDa apoprotein of LHC IId, a minor light-harvesting antenna component of Photosystem II, has been isolated and subjected to N-terminal protein sequencing. A sequence of 66 residues was obtained which contains regions of considerable homology to both those reported for LHC II and LHC I, but which is obviously distinct from them. The proposed occurrence of an identical 21 kDa LHC subunit in both photosystems I and II is shown to be incorrect.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
