Depositor Comments

Endonuclease that specifically degrades the RNA of RNA-DNA hybrids. Participates in DNA replication; helps to specify the origin of genomic replication by suppressing initiation at origins other than the oriC locus. Along with the 5'-3' exonuclease of pol1, it removes RNA primers from the Okazaki fragments of lagging strand synthesis, and it defines the origin of replication for ColE1-type plasmids by specific cleavage of an RNA pre-primer.

The plasmids in the Open Enzyme collection contain genetic parts and are not functional by themselves. Researchers can clone these enzymes into an expression vector of their choice and then transform into E. coli bacteria for expression and purification.
