title: Mercaptoethanol assists in cleaving a cysteine/cystine-free protein into its subunits.
abstract: The alpha-mannosidase from Canavalia ensiformis is devoid of cysteine and cystine. Nevertheless, its cleavage into subunits is facilitated by the presence of mercaptoethanol in the denaturing buffer.
