CryoEM structure of human enterovirus D68 abortive product 2 (pH 7.2 and 4 degrees Celsius)

Molecular basis for the acid-initiated uncoating of human enterovirus D68.

A combination of the following approaches was used: (1) model rebuilding using Coot, (2) real space refinement using Phenix, (3) reciprocal space refinment using REFMAC5 (as in standard crystallographic refinement).
