Tanaka S, et al. (1996) Systematic mapping of autonomously replicating sequences on chromosome V of Saccharomyces cerevisiae using a novel strategy. Yeast 12(2):101-13
Abstract: We have developed a new procedure for easy and rapid identification of autonomously replicating sequences (ARSs) and have applied it to the analysis of chromosome V of Saccharomyces cerevisiae. The procedure makes use of the ordered lambda phage clone bank of this chromosome that we have constructed, and includes transposition of a mini-transposon and selection of transposon-containing derivatives, isolation of their DNA and circularization at their cos-ends, transformation of yeast cells with the circularized DNA, and scoring transformation frequency. The transposon used was derived from Tn5supF, contained the yeast LEU2 gene, and was placed, together with the hyperactive transposase gene, on a mini-F plasmid for stable maintenance in Escherichia coli K-12. Sixteen regions of chromosome V showing ARS activity were identified, of which 12 were newly found in this work. Thus, the procedure will be useful for systematic genomic scale analysis of ARSs in yeast and related organisms in which ordered clone banks have been established. The average distance between adjacent ARS-containing regions was approximately 40 kb. Two-dimensional gel electrophoretic analysis of chromosome replication indicated that one of the newly identified ARSs was functional as an actual in situ replication origin, at least under the conditions employed.
