Lys212B | Asp279 | Asp252B | |
---|---|---|---|
Deprotonation of ICT | 1.5 | 12.2 | 16.6 (±0.7) |
Reduction of NADP+ | 13.4 | 21.4 | 24.0 (±1.6) |
The Helmholtz free energy for Asp252B as the base is from this work, while the Gibbs free energies for the pathways with Lys212B and Asp279 as the base are from ref (93).
