 2B4C RIGID BODY FIT Chimera
Three structures of HIV-1 gp120 bound to sCD4 were fit into the HIV-1 Env trimer portion of the map.
REAL 1OP5 RIGID BODY FIT Chimera
2G12 Fab structures were fit by rigid body fitting using the UCSF Chimera volume fit option, simulating a map at an estimated resolution of 20 Angstrom.
