GO_REF:0000002

Gene Ontology annotation through association of InterPro records with GO terms

GO_REF:0000043

Gene Ontology annotation based on UniProtKB/Swiss-Prot keyword mapping

The "Antiviral defense" keyword was automatically assigned and may not be appropriate for group II intron maturases which are mobile genetic elements rather than defense systems.

Global features of the <i>Pseudomonas putida</i> KT2440 genome sequence

The KT2440 genome harbors group II introns within genomic islands.
Provides genomic context supporting classification of PP_0635 as a group II intron-associated RT/maturase.

Structure-functional characterization of <i>Lactococcus</i> AbiA phage defense system

Defense RTs (Abi/retrons) are structurally and functionally distinct from group II intron maturases.
Group II intron maturases are associated with intron RNA splicing/mobility, not phage defense.
Provides key evidence for distinguishing defense RTs from mobile element RTs.
