Group I introns that encode homing endonuclease genes (HEGs) are highly invasive genetic
elements. Their movement into a homologous position in an intron‐less allele is termed …

Group I introns are autonomous genetic elements that can catalyze their own excision from
pre-RNA. Understanding how group I introns move in nuclear ribosomal (r) DNA remains an …

Homing endonucleases are encoded by open reading frames that are embedded within
group I, group II and archael introns, as well as inteins (intervening sequences that are …

The LAGLIDADG protein family includes the first identified and biochemical# ly
characterized intron# encoded proteins (Dujon 19801 Lazowska et al. 19801 Jacquier and …

Ribosomal DNA (rDNA) is a specialised chromosomal location that is dedicated to high-
level transcription of ribosomal RNA genes. Interestingly, rDNAs are frequently interrupted …

Group I introns are thought to be self‐propagating mobile elements, and are distributed over
a wide range of organisms through horizontal transmission. Intron invasion is initiated …

LAGLIDADG homing endonucleases (LHEs) are DNA cleaving enzymes, also termed
'meganucleases' that are employed as gene-targeting reagents. This use of LHEs requires …

Homing endonucleases are a diverse collection of proteins that are encoded by genes with
mobile, self-splicing introns,,. They have also been identified in self-splicing inteins (protein …

The myxomycete Didymium iridis (isolate Panama 2) contains a mobile group I intron named
Dir. S956-1 after position 956 in the nuclear small subunit (SSU) rRNA gene. The intron is …

Sequence analysis of chloroplast and mitochondrial large subunit rRNA genes from over 75
green algae disclosed 28 new group I intron-encoded proteins carrying a single …
