Fig. 5From: An improved secretion signal enhances the secretion of model proteins from Pichia pastorisSeparate analysis of the two differences that distinguish pro-α-factor(I) from pro-α-factor. The experiment was performed as in Fig. 2a, except that the signals were not normalized and the Ost1 signal sequence was used together with either pro-α-factor, or pro-α-factor(I), or the MUT1 or MUT2 variant of the α-factor pro region. a.u. arbitrary unitsBack to article page
