We have previously peported that the replication orgin region located near theura4gene on chromosome III of the fission yeast,Schizosaccharomyces pombe, contains three closely spaced origins, each associated with an autonomously replicating sequence (ARS) element. Here we report the nucleotide sequences of two of these ARS elements,ars3002andars3003. The two ARS elements are located on either side of a transcribed 1.5 kb open reading frame. Like 11 otherS. pombeARS elements whose sequences have previously been determined in other laboratories, the 2 new ARS elements are unusually A+T-rich. All 13 ARS elements contain easily unwound stretches of DNA. Each of the ARS elements contains numerous copies, at a higher than expected frequency, of short stretches of A+T-rich DNA in which most of the Ts are on one strand and most of the As are on the complementary strand. We discuss the potential significance for ARS function of these multiple asymmetric A+T-rich sequences.
