Isolation and characterization of PRT1, a gene required for the initiation of protein biosynthesis in Saccharomyces cerevisiae.
We isolated a cloned DNA fragment containing PRT1, a gene required for the initiation of protein biosynthesis in Saccharomyces cerevisiae, by complementation of the temperature-sensitive prtl-1 mutation. The entire PRT1 gene is contained within a 3.2-kilobase-pair segment of the cloned DNA in YEp13 H1.2. Southern blot analysis demonstrated that PRT1 is a single copy gene which is transcribed into a 2.3-kilobase RNA. We determined the direction of transcription and mapped the 5' and 3' ends of the gene.
