Abstract Let (R , *) be a 2-torsion free *-prime ring with involution *, L ≠ 0 be a square closed *-Lie ideal of R and α, β automorphisms of R commuting with *. An additive mapping F : R → R is called a generalized (α, β )-derivation on R if there exists an (α, β )-derivation d such that F (xy ) = F (x )α (y ) + β (x )d (y ) holds for all \({x, y \in R}\) . In the present paper, we shall show that \({L\subseteq Z(R)}\) such that R is a *-prime ring admits a generalized (α, β )-derivation satisfying several conditions, but associated with an (α, β )-derivation commuting with *.
