S. cerevisiae Nip1 (with C-terminal TEV cleavage site and strep-II tag), Sui1 and Tif5B6 (with N-terminal 7xHis tag and TEV cleavage set) coding sequences with intervening ribosome binding sites and other cis-elements for expression as a polycistron, T7 theta 10 promoter (and corresponding terminator after polycistron).
