Extended Data Fig. 3: Electron density for selected components of STP10 structures.

From: Molecular mechanism of sugar transport in plants unveiled by structures of glucose/H+ symporter STP10

Extended Data Fig. 3

a) Backbone representation of the STP10 outward structure with all heterologous molecules found in the density highlighted. Besides STP10 the model contains 1 glucose, 2 acetate, 1 PEG 458, 4 monoolein molecules and 157 waters. The four inserts highlight the quality of the electron density displayed by the weighted 2FoFc density at 1.5 sigma for the PEG and acetate, glucose, intracellular cysteines and of the monoolein, which was weaker and is clearer at lower sigma levels than 1.5. b) Backbone representation of the STP10 inward structure with all the heterologous molecules found in the density highlighted. Besides STP10 the model contains 1 glucose, 1 chloride ion, 2 OGNG and 9 waters. The four inserts highlight the quality of the electron density displayed by the weighted 2FoFc density at 1.0 sigma for the two OGNG, glucose and the disulfide bridge.
