Differences in deuterium uptake of the AtPhyB wildtype and the ΔNTE variant in the Pr state.
Pr(Δ) − Pr(WT) reveals possible interactions sites of the N terminal extension. The NTE is shown as spheres and coloured according to their deuterium exchange rate. Black labelled amino acids are involved in the binding of the phytochrome interaction factor.
