Figure 7.
Effect of temperature on protein splicing. Mixtures of MUNΔ and UCΔH were reconstituted under standard conditions at 4°C, supplemented with 1.25 mM DTT to induce splicing and incubated for 6 hr at the temperatures indicated. Protein splicing was assayed by Western blot analysis with anti-His-tag antibody, and the relative amounts of MH were estimated by densitometry of the Western blot.
