Abstract:
:Affinity chromatography based on the reaction between SH groups in protein and +HgC6H4CO groups in the p-mercuribenzoylaminoethyl derivative of Sepharose 4B was examined with a crude preparation of calf thymus cysteine-containing histone. Adsorption of the histone onto the column by specific coupling was found to be optimal in 0.1 M citrate buffer, pH 5.5, containing 5M urea to prevent any aggregation of histones and their non-specific adsorption onto the column, and elution from the column was successfully performed by cleavage of the resulting S-Hg bond with urea-buffer solution containing 0.05 M 2-mercaptoethanol. Under these conditions both the adsorption and elution were quantitative; no adsorption was observed when either SH-blocked histone or unsubstituted Sepharose was used. The cysteine-containing histone thus recovered, after further purification by Bio-Gel P-60 chromatography to remove some cysteine-containing nonhistone proteins contaminating the starting material, showed a single band on polyacrylamide gel electrophoresis and an amino acid composition agreeing with the known sequence of this histone.

Although the peroxisomal membrane appears to be impermeable to CoASH, peroxisomes contain their own pool of CoASH.
