Abstract
It is shown that similarly to massless superparticle, classical global symmetry of the Berkovits twistor string action is infinite-dimensional. We identify its superalgebra, whose finite-dimensional subalgebra contains superalgebra. In quantum theory this infinite-dimensional symmetry breaks down to one.
