This paper presents evidence for light-mediated degradation of isolated light-harvesting proteins (Lhc2) and involvement of oxygen free radicals in the process. The time course of light harvesting photodestruction is much slower than that of D1 protein (requiring hours for complete breakdown). By use of mass spectrometry and amino acid sequencing, it has been revealed that the primary cleavages take place in the hydrophilic portion of the NH(2) region where oxygen-containing radicals attack… CONTINUE READING
