Depositor Comments

QS cDNA was obtained by PCR using primers PR53
(aatggtacccaacatgaacaccatcccggcac) and PR54 (aatgcggccgctcaagatatttgcgttgcaattc) using a
cosmid, pLorist-HO35F3 from the Fungal Genetics Stock Center, as the template. The PCR
fragment was initially cloned into pPAC5C-PL using Acc65 I and NotI to obtain the QS gene
containing a single intron. The intron was subsequently removed by creating two PCR products that
were cloned using 3-way ligation into pCDNA3.1-Mys-His-A (Invitrogen) using Acc65I and NotI and
blunt ends at the exon-exon junction. The primers used to create the first exon are: PR53 (see
above) + PR190 (agagcctagaggtactctgtgggcgg); and the second exon are: PR58
(tggtcggcgcccaattcc) + PR54 (see above).

A stop codon precedes the Myc and His tags.
