Abstract excerpt
The amino acid residues essential for the catalytic activity of ribonuclease H (RNase H) from Escherichia coli (E. coli) were identified by site-directed mutagenesis. It has been proposed by computer analysis that E. coli RNase H has homologous amino acid sequence with the RNase H domains of various retroviral reverse transcriptases (RTs) (Johnson, M. S., McClure, M. A., Feng, D. F., Gray, J., and Doolittle, R....
