FIG. 1.

Nucleotide sequence of the P. chrysosporium qr cDNA. The amino acid sequence of the predicted translation product is shown below the nucleotide sequence. The qr coding region is flanked by a 59-bp 5′ noncoding region and a 132-bp 3′ noncoding region, excluding the poly(A) tail. The initiation codon is followed by an apparent 71-amino-acid leader sequence, which is underlined. The experimentally determined N-terminal amino acid sequence of the isolated QR protein is overlined. The two KEX2 cleavage sites in the leader sequence are enclosed in boxes. The dots indicate the potential glycosylation sites at residues 11 and 223.
