Quantum chemical calculations support a mechanism of light-induced changes in BLUF photoreceptor proteins involving rotation/tautomerization transformations of a conserved Gln residue near the flavin chromophore.

To verify the specific mechanism of light-induced changes involving the rotation/tautomerization transformations with the conserved Gln residue near the flavin chromophore, we performed accurate quantum chemical calculations

Comparisons

Source-backed strengths

The method combines QM treatment at the B3LYP/cc-pVDZ level with MM treatment using AMBER, and it was applied to both geometry optimization and vibrational frequency analysis. In the cited work, its predictions were reported to agree excellently with experiment and to support a specific mechanistic model involving conserved Gln rotation/tautomerization.
