Protonation/deprotonation reactions triggered by photoactivation of photoactive yellow protein from Ectothiorhodospira halophila.

The Journal of biological chemistry - 18 Jun 1999

Abstract excerpt

Light-dependent pH changes were measured in unbuffered solutions of wild type photoactive yellow protein (PYP) and its H108F and E46Q variants, using two independent techniques: transient absorption changes of added pH indicator dyes and direct readings with a combination pH electrode. Depending on the absolute pH of the sample, a reversible protonation as well as a deprotonation can be observed upon formation of...
