Kinetic analysis of hairpin-ribozyme constructs used in this study. Substrate-cleavage reactions were carried out under single-turnover conditions. For each construct (circles, S9-linked; diamonds, C3-linked; triangles, junctionless, JL) time courses were fitted to a double-exponential kinetic equation (see §2.4). Inset: representative gel images of the cleavage time course for the S9 and JL constructs; similar results were observed for the C3 construct (data not shown). Bands represent 5′-Cy5-labeled 13-mer substrate and 8-mer product strands. |
