Protein structure evaluation based on gel filtration data

A new protein of unknown structure has been purified. Gel filtration chromatography reveals that the native protein has a molecular weight of 240,000. Chromatography in the presence of 6 M guanidine hydrochloride yields only a peak for a protein of Mr 60,000. Chromatography in the presence of 6 M guanidine hydrochloride and 10 mMβ-mercaptoethanol yields peaks for proteins of Mr 34,000 and 26,000. Explain what can be determined about the structure of this protein from these data.
