dc.description.abstract | The nuclear-encoded Chl a/b and Chl a/c antenna proteins of photosynthetic eukaryotes are part of an extended family of proteins that also includes the early light-induced proteins (ELIPs) and the 22 kDa intrinsic protein of PS II (encoded by psb S gene). All members of this family have three transmembrane helices except for the psb S protein, which has four. The amino acid sequences of these proteins are compared and related to the three-dimensional structure of pea LHC II Type I (Kühlbrandt and Wang, Nature 350: 130–134, 1991). The similarity of psb S to the three-helix members of the family suggests that the latter arose from a four-helix ancestor that lost its C-terminal helix by deletion. Strong internal similarity between the two halves of the psb S protein suggests that it in turn arose as the result of the duplication of a gene encoding a two-helix protein. Since psb S is reported to be present in at least one cyanobacterium, the ancestral four-helix protein may have been present prior to the endosymbiotic event or events that gave rise to the photosynthetic eukaryotes. The Chl a/b and Chl a/c antenna proteins, and the immunologically-related proteins in the rhodophytes may have had a common ancestor which was present in the early photosynthetic eukaryotes, and predated their division into rhodophyte, chromophyte and chlorophyte lineages. The LHC I-LHC II divergence probably occurred before the separation of higher plants from chlorophyte algae and euglenophytes, and the different Types of LHC I and LHC II proteins arose prior to the separation of angiosperms and gymnosperms. | en_US |
