Genome Property Definition Page

Namesporadically distributed four-gene operon
DescriptionA conserved gene four-gene neighborhood is found sporadically in a phylogenetically broad range of bacteria: Nocardia farcinica, Symbiobacterium thermophilum, and Streptomyces avermitilis (Actinobacteria), Geobacillus kaustophilus (Firmicutes), and Azoarcus sp. EbN1 and Ralstonia solanacearum (Betaproteobacteria). It is found near CRISPR repeats in Geobacillus kaustophilus HTA426, whose genome has no identified Cas proteins. It is found near a cas gene cluster and its CRISPR repeats in another species.
