Oxidatively Modified Residues in the Vicinity of Pheo_D1 and Q_A.

Individual residues are listed along with the modifications observed. For a complete list of oxidative modification types, the amino acids targeted, and mass modifications searched for in this study, as well as structures arising from these oxidative modifications, see [50], [51]. Key: ca, carbonyl addition (+14 Da); gam, Glu/Asp modification (decarboxylation and oxidation, −30 Da); go, general oxidation (+16 Da). Oxidative modification of these residues was originally reported in Frankel et al. [20]. aBuried residues not adjacent to apparent cavities/channels. bSurface-exposed residues.
