Inner workings of a cellular nanomotor revealed

Our cells produce thousands of proteins but more than one-third of these proteins can fulfill their function only after migrating to the outside of the cell. While it is known that protein migration occurs with the help of various 'nanomotors' that push proteins out of the cell, little is known about their precise mechanical functioning. New research by Anastassios Economou (KU Leuven) and his team reveals the inner workings of one such nanomotor, called SecA, with new clarity.
