Molecular dynamics guided engineering of Aequorea victoria Green Fluorescent Protein chromophore interactions generates a brighter variant with improved photobleaching resistance

Rochelle D. Ahmed, William David Jamieson, Danoo Vitsupakorn…·D. Dafydd Jones

The paper engineers a brighter and more photostable variant of avGFP by modifying chromophore interactions, resulting in improved fluorescence and resistance to photobleaching.

Chromophore charge-state switching through copper-dependent homodimerisation of an engineered green fluorescent protein.

Rochelle D. Ahmed, Danoo Vitsupakorn, Kieran D Hartwell…·D. Dafydd Jones

This paper engineers a green fluorescent protein that changes its chromophore charge state through copper-dependent homodimerisation, resulting in a 30-fold fluorescence emission ratio change.
