ColE1 DNA replication is initiated by RNA II and inhibited by RNA I. Control of the replication occurs through the interaction between RNA I and RNA II. Therefore, RNases involved in the metabolism of RNA I and RNA II are expected to play a key role in the control of the ColE1 plasmid replication. RNase H, RNase E, RNase III, RNase P, and polynucleotide phosphorylase carry out the many specific reactions of the RNA metabolism.
ColE1 DNA复制由RNA II起始，并受RNA I抑制。复制的控制通过RNA I和RNA II之间的相互作用实现。因此，参与RNA I和RNA II代谢的核糖核酸酶有望在ColE1质粒复制的控制中发挥关键作用。核糖核酸酶H、核糖核酸酶E、核糖核酸酶III、核糖核酸酶P和多核苷酸磷酸化酶参与RNA代谢的许多特定反应。
