    • 3H]trapoxin indicated that the radiolabel is released into solution after protein denaturation with SDS or guanidinium hydrochloride. Thus, trapoxin binding proteins were expected to elute from the affinity matrix with SDS (J Taunton, C. A. Hassig, S. L Schreiber, unpublished observations)

    • To obtain enough trapoxin binding protein for micro-sequencing, we prepared nuclear ammonium sulfate pellets from 15 bovine thymuses as described (7). Sedimented proteins were resuspended in and dialyzed against buffer A [20 mM bis-tris (pH 7.2), 20 mM NaCI, and 10% glycerol] for 12 hours and brought to pH 5 8 by dialyzing against buffer A (pH 5.8) for 30 min After centrifugation, the dialysate (∼650 mg of protein) was loaded onto a Q Sepharose FF column (2.6 cm by 10 cm, Pharmacia), and the column was washed with 120 ml of buffer A (pH 5.8). Proteins were eluted with a 400-ml linear gradient of 20 to 600 mM NaCl in buffer A. Fractions (10 ml; each fraction contained 1 ml of 1 M tns, pH 8, to neutralize the acidic buffer A) were assayed for trapoxin binding activity. Tween-20 was added to active fractions at a final concentration of 0 05%, and these fractions were incubated with K-trap affinity matrix for 16 hours (25 μl per milliliter of Q fraction). After the matrix was washed three times with phosphate-buffered saline, bound proteins were eluted by boiling in 40 μl of SDS sample buffer per 25 μl of matrix. SDS eluates were combined and the proteins resolved by SDS-(PAGE) (12% gel) and transferred to polyvinylidene difluoride membrane (Bio-Rad) Staining with Ponceau S revealed two major bands (46 and 50 kD) The excised bands were proteolytically digested, and the peptide fragments purified by high-performance liquid chromatography were sequenced at the Harvard Microchemistry Facility.
