title: Chlorophyll a/b-binding proteins: an extended family.
abstract: A large proportion of the chlorophyll in a plant is engaged in harvesting light energy and transferring it to the photochemical reaction centres. These 'antenna' chlorophylls are non-covalently bound to specific proteins to form chlorophyll-protein complexes. The chlorophyll a/b-binding (CAB) polypeptides are encoded by an extended family of nuclear genes. It has recently been discovered that other proteins not known to bind chlorophyll, the early light-inducible proteins (ELIPs), are also related and could be considered part of this family. We suggest that the latter proteins may be involved in pigment biosynthesis or in assembly of the thylakoid membrane.
