Determination of surface p K a values on PSII protein PsbO : Being close to the proton release side of Photosystem II and equipped with numerous surface carboxylate groups, PsbO is an appealing model to study side‐chain‐protonation reactions. Using solution NMR techniques, we were able to determine the p K a values of 21 out of 22 carboxylate groups, revealing a site‐specific distribution as illustrated on the cover.
