The pKa of the Schiff base (SBH+) of D193N was ~10.1-10.0 (at XH+) and ~11.4-11.6 (at X) depending on the protonation state of a certain residue (designated by X) and independent of Cl, whereas those of the wild type and D193E were >12.

87. Tyr-199 and charged residues of pharaonis Phoborhodopsin are important for the interaction with its transducer. - Sudo, Yuki; Iwamoto, Masayuki; Shimono, Kazumi; Kamo, Naoki
Kamo, submitted for publication) showed that analysis of flash-photolysis data of a complex between D75N and the truncated pHtrII (t-Htr) give a good estimate of the dissociation constant KD in the dark.
