We study the single top production mediated by flavor-changing neutral current via both of the and vertices (here q represents c and u quarks) in ep collisions at two colliders HERA and THERA. The contribution of the second vertex becomes even more important as the couplings take more improved values provided by the higher luminosities of colliders. In addition to these improvements, if the CM energy of the collider is also increased, the production will be dominated by the anomalous vertex.
