in order to explore the correlation between protease susceptibility and conformational stability of a protein , the proteolytic degradation by trypsin , subtilisin and pronase p of the wild-type alpha subunit of tryptophan synthase from escherichia coli and of its two mutant proteins was studied by measuring circular dichroism at 222 nm at various ph values at 37 degrees c .
