turbulent energy in UEqn / divDevReff

I'm wondering where the "2/3 k delta_ij" part of the eddy viscosity model is included into the UEqn of solvers like interFoam or (for example) the divDevReff part of the incompressible kEpsilon model. I only find the turbulent "viscosity" nu_t -> nuEff = nu + nu_t added, so turbulence is represented in the fvm::laplacian(nuEff,U) part, but where is "2/3 k delta_ij".
Thank you in advance for a hint.
