Characterization of the C-terminal DNA-binding/DNA endonuclease region of a group II intron-encoded protein.

Abstract excerpt

Group II intron retrohoming occurs by a mechanism in which the intron RNA reverse splices directly into one strand of a double-stranded DNA target site, while the intron-encoded reverse transcriptase uses a C-terminal DNA endonuclease activity to cleave the opposite strand and then uses the cleaved 3' end as a primer for reverse transcription of the inserted intron RNA. Here, we characterized the C-terminal...
