Background Streptococcus agalactiae, also known as Group B Streptococcus (GBS), is a Gram-positive bacterium that colonizes the gastrointestinal and genitourinary tract of humans. This bacterium has also been isolated from various animals, such as fish and cattle. Non-coding RNAs (ncRNAs) can act as regulators of gene expression in bacteria, such as Streptococcus pneumoniae and Streptococcus pyogenes....
The attC sites are well-known integrase-targeted elements involved in the insertion and excision of gene cassettes from integrons. Recently, functional analysis of Sma.I2, a class C-attC group II intron, showed that this mobile element invades the attC sites through a specific process. The analysis of genomic data indicates that class C-attC group II introns are independently acquired by their bacterial...
