Crystal structure of RNase H1 from halophilic archaeon Halobacterium salinarum NRC-1
Function
[RNH_HALSA] Nuclease that specifically degrades the RNA of RNA-DNA hybrids; seems to act exonucleolytically on RNA/DNA hybrids. Endonucleolytically removes RNA primers from the Okazaki fragments of lagging strand synthesis on its own. Complements the temperature-sensitive phenotype of an E.coli double rnhA/rnhB (RNase H) disruption mutant.[1]
About this Structure
