cryo-EM buffer pH 7.5；Buffer was filtered through 0.44 um filter and degassed.
cryo-EM vitrification conditions Cryogen ETHANE；Sample was applied to a glow-discharged holey carbon grid. 3 uL actin was incubated for 60 seconds. 3 uL of myosin VI was added and incubated for 60 seconds. 3 uL solution was removed. An additional 3 uL of myosin VI was applied. After 60 seconds, 3 uL solution was removed, and the grid was blotted for 3 seconds from the backside with filter paper.

This page presents structural evidence recorded in PDB/mmCIF.“No recorded non-water small molecule” does not prove that the experimental sample was ligand-free; experimental conditions belong to the PDB experiment, while ligands and copy counts are shown for each biological assembly.
