| Type: | Family | Name: | Chlorophyll A-B binding protein |
| Description: | The light-harvesting complex (LHC) consists of chlorophylls A and B and the chlorophyll A-B binding protein. LHC functions as a light receptor that captures and delivers excitation energy to photosystems I and II with which it is closely associated. Under changing light conditions, the reversible phosphorylation of light harvesting chlorophyll a/b binding proteins (LHCII) represents a system for balancing the excitation energy between the two photosystems [].The N terminus of the chlorophyll A-B binding protein extends into the stroma where it is involved with adhesion of granal membranes and photo-regulated by reversible phosphorylation of its threonine residues []. Both these processes are believed to mediate the distribution of excitation energy between photosystems I and II.This family also includes the photosystem II protein PsbS, which plays a role in energy-dependent quenching that increases thermal dissipation of excess absorbed light energy in the photosystem []. | Short Name: | Chloroa_b-bind |
