HDX results mapped on NbUGT72AY1.

Differential HDX results obtained after the addition of scopoletin, UDP, and a combination of both to the protein were color-mapped onto the predicted 3D structure of the open conformer of NbUGT72AY1.

(A) After addition of scopoletin (in sphere display), (B) after addition of UDP, and (C) after addition of scopoletin and UDP.

(D) Scopoletin and UDP-Glc (both in sphere display) are shown in the open conformer of the predicted structure of NbUGT72AY1 (HDX results of UDP/scopoletin are color-mapped).

(E) Scopoletin and UDP-Glc are buried in the closed conformer of NbUGT72AY1.

(F) Flexible loop (1) is highlighted in the NbUGT72AY1 model (green, closed conformation; red, open conformation; HDX results of scopoletin are color-mapped). Two additional closing loops are displayed.
