Genetic immobilization of RNase Rny1p at the Saccharomyces cerevisiae cell surface.

Genetic immobilization of the yeast RNase Rny1p was performed by creating a hybrid protein containing the signal sequence of the S. cerevisiae cell wall protein Ccw12p followed by the catalytic part of the Rny1p (amino acids 19 to 293) and additionally 73 amino acids of the Ccw12p including the GPI-anchoring signal. The construct was expressed in S.
