FIGURE 8.

Proposed U6 recycling pathway from post-catalytic spliceosomes for wild-type (top) and U4–G41U/U6–A62G,A91G triple mutant (bottom) cells. Asterisks indicate mutations. Dashed line indicates a reduced forward equilibrium constant that results in an increased accumulation of U2/U6** snRNP. The Lsm2-8 proteins (not shown) likely act in concert with Prp24.
