Abstract:
The A subunit of DNA gyrase in mycobacteria is frequently subjected to splicing events as its gene, gyrA, harbours an insertion encoding an intein. Investigation of a number of different isolates of Mycobacterium kansasii, Mycobacterium malmoense, Mycobacterium marinum, Mycobacterium ulcerans and Mycobacterium xenopi demonstrated that the presence of GyrA inteins is not random but a taxonomic character specific for a given taxon at a species or subspecies level.
