We construct the universal enveloping preassociative and postassociative algebra for a pre-Lie and a post-Lie algebra, respectively. We show that the pairs (pre-Lie, pre-As) and (post-Lie, post-As) are Poincaré-Birkhoff-Witt-pairs; for the first this is a reproof of the result of V. Dotsenko and P. Tamaroff.
Keywords: Rota-Baxter operator, Groebner-Shirshov basis, pre-Lie algebra, post-Lie algebra, preassociative algebra, dendriform algebra, postassociative algebra.
