Let HT=C[T,T-1] be the Hopf algebra of symmetries of a lattice of rank 1, or equivalently, HT is the group algebra of a free Abelian group with one generator T. We construct conformal algebras, vertex Poisson algebras and vertex algebras with HT as symmetry. For example, the Hamiltonian structure for the infinite Toda lattice gives rise to an HT-vertex Poisson structure on a free difference algebra. Examples of HT-vertex algebras are constructed from representations of a class of infinite dimensional Lie algebras related to HT in the same way loop algebras are related to the Hopf algebra HD=C[D] of infinitesimal translations used in the usual vertex algebras.
