THIS IS A MODEL OF THE PARM ANTIPARALLEL ANTIPARALLEL DOUBLET BASED ON CRYOEM DATA. TWO COPIES OF THE PARM AMPPNP CRYO-EM FILAMENT STRUCTURE WERE PLACED IN AN ANTIPARALLEL ORIENTATION. ANTIPARALLEL ASSIGNMENT WAS DONE USING CRYO-EM ALIGNMENT. THIS IS A MODEL OF THE PARM ANTIPARALLEL DOUBLET CONSTRUCTED USING CRYO-EM DATA. ONLY C-ALPHAS HAVE BEEN DEPOSITED.
