PROCESS FOR PREPARING FGF21 WITH LOW DEGREE OF O-GLYCOSYLATION
摘要:
Expression of FGF21 in a S. cerevisiae pmt2 knock out strain reduces the O-glycosylation significantly and does not decrease the expression level. Expression in mkc7 knock out strain can decrease degradation of FGF21 and analogues thereof. Point mutations at position R17 and R36 can decrease degradation of FGF21 and analogues thereof when they are expressed in yeast.
