Structural features in the C-terminal region of the Sinorhizobium meliloti RmInt1 group II intron-encoded protein contribute to its maturase and intron DNA-insertion function.

Abstract excerpt

Group II introns are both catalytic RNAs and mobile retroelements that move through a process catalyzed by a RNP complex consisting of an intron-encoded protein and the spliced intron lariat RNA. Group II intron-encoded proteins are multifunctional and contain an N-terminal reverse transcriptase domain, followed by a putative RNA-binding domain (domain X) associated with RNA splicing or maturase activity and a...
