IS990, a new species-specific insertion-sequence-related element of the Mycobacterium tuberculosis complex

Microbiology (Reading). 1998 Dec:144 ( Pt 12):3407-3412. doi: 10.1099/00221287-144-12-3407.

Abstract

The structure and distribution of 1S990, a new Mycobacterium tuberculosis DNA sequence with homology to characterized insertion sequences (ISs), were investigated. IS990 was related to IS elements of the IS3 family and was present as a single copy in all 21 investigated M. tuberculosis strains, two Mycobacterium bovis strains and two M. bovis BCG strains. The sequence appears to be specific for the M. tuberculosis complex. The element carries two frameshift mutations and appears to be defective.
