abstract：:A new insertion sequence, IS1634, has been identified in Mycoplasma mycoides subsp. mycoides small-colony type (SC). IS1634 shows structural and functional similarities to IS1549 of Mycobacterium smegmatis and with it seems to form a new class or family of insertion sequences. IS1634 has a size of 1,872 bp, including ...
