| Abstract |
The PRB1 gene of Saccharomyces cerevisiae encodes the vacuolar endoprotease protease B. We have determined the DNA sequence of the PRB1 gene and the amino acid sequence of the amino terminus of mature protease B. The deduced amino acid sequence of this serine protease shares extensive homology with those of subtilisin, proteinase K, and related proteases. The open reading frame of PRB1 consists of 635 codons and, therefore, encodes a very large protein (molecular weight, greater than 69,000) relative to the observed size of mature protease B (molecular weight, 33,000). Examination of the gene sequence, the determined amino-terminal sequence, and empirical molecular weight determinations suggests that the preproenzyme must be processed at both amino and carboxy termini and that asparagine-linked glycosylation occurs at an unusual tripeptide acceptor sequence. |
