furthermore , the nh2-terminal sequence of a proteolytic derivative ( pe ' 2 ) that contains the bulk of pe2 and that is generated after exposure of the microsomal vesicles to proteolytic enzymes is identical to that of intact pe2 , strongly suggesting that only a cooh-terminal portion of pe2 is excluded from translocation across the microsomal membrane .
