Excision of the En/Spm transposable element of Zea mays requires two element-encoded proteins

M Frey et al. EMBO J. 1990 Dec.

Abstract

An excision assay system for En/Spm was developed in transgenic tobacco. The characteristics of excision and integration are similar to the natural system of Zea mays. In this transgenic model system two En/Spm encoded trans-acting functions, TNPA and TNPD, are required for excision. A biochemical model for transposition is proposed that might also be applicable to other transposable elements.
