Abstract

An interaction between the origin recognition complex (ORC) and Cdc6p is the first and a key step in the initiation of chromosomal DNA replication. We describe the assembly of an origin-dependent complex containing ORC and Cdc6p from Saccharomyces cerevisiae. Cdc6p increases the DNA binding specificity of ORC by inhibiting non-specific DNA binding of ORC. Cdc6p induces a concomitant change in the conformation of ORC and mutations in the Cdc6p Walker A and Walker B motifs, or ATP-gamma-S inhibited these activities of Cdc6p. These data suggest that Cdc6p modifies ORC function at DNA replication origins. On the basis of these results in yeast, we propose that Cdc6p may be an essential determinant of origin specificity in metazoan species.
