Proteinase yscE, the yeast proteasome, is a member of the nonlysosomal, high molecular mass (approximately 700 kDa) multifunctional proteinase complexes that are highly conserved from yeast to man. We have isolated mutants defective in one of the three proteolytic activities of the enzyme complex, i.e. in cleavage of peptide bonds after acidic amino acids. Using one of these mutants (pre4-1), we cloned the PRE4 gene and uncovered an open reading frame with 266 amino acids coding for a predicted… CONTINUE READING
