The distance between the TATAAAAG box and initiator element of the strong adenovirus major late promoter was systematically altered to determine the optimal spacing for simultaneous recognition of both elements. We find that the TATAAAAG element is strongly dominant over the initiator for specification of the start site. The wild type spacing of 23 base pairs between TATAAAAG and +1A is optimal for promoter strength and selective recognition of the A-start. Initiation is constrained to a window spaced 19-26 base pairs downstream of (-31)-TATAAAAG-(-24), and A-starts are favored over alternate starts only when spaced between 21 and 25 base pairs downstream of TATAAAAG. We report an expanded TATAAAAG and initiator promoter consensus for vertebrates and plants. Plant promoters of this class are (A-T)-rich and have an A-rich (non-template strand) core promoter sequence element downstream of +1A. 相似文献
