We study the uniform description of deformedalgebras of typeincluding the supersymmetric case in terms of the quantum toroidalalgebra. In particular, we recover the deformed affine Cartan matrices and the deformed integrals of motion. We introduce a comodule algebraoverwhich gives a uniform construction of basic deformedcurrents and screening operators in typesincluding twisted and supersymmetric cases. We show that a completion of algebracontains three commutative subalgebras. In particular, it allows us to obtain a commutative family of integrals of motion associated with affine Dynkin diagrams of all non-exceptional types except. We also obtain in a uniform way deformed finite and affine Cartan matrices in all classical types together with a number of new examples, and discuss the corresponding screening operators.
