Dynamin ring constricts the membrane by "loosening."

Caption

Dynamin assembles into a ring around the neck of a forming vesicle and utilizes GTP hydrolysis energy to constrict and sever the membrane. The simulation reveals that the dynamin ring expands (loosens) upon GTP hydrolysis, which indirectly forces the adjacent membrane tube to narrow.
