New software brings lower-resolution cryo-EM maps into focus

An example of the secondary structure detection in cryo-EM density map using Emap2Sec. A left is an EM map of archaeal 20S proteasome (EMDB ID: EMD-1733). At right are detected secondary structures by Emap2Sec. Points in magenta are the positions of detected alpha helices; yellow points are detected beta strands, and green points are for […]
