Donald Yau defined the notion of pseudo symmetric Cat-enriched multifunctor between Cat-enriched multicategories and proved that Mandell's inverse K-theory multifunctor is pseudo symmetric. We prove a coherence theorem for pseudo symmetric Cat-enriched multifunctors. As an application we prove that pseudo symmetric Cat-enriched multifunctors, and in particular Mandell's inverse K-theory, preserve Σ-free E_n-algebras (n=1,2,...,∞), at the cost of changing the parameterizing Σ-free E_n-operad O for the Σ-free E_n-operad O x EΣ_*.
