Inverted repeat sequences identified upstream of the cutB genes of various mycobacteria. The conserved inverted repeats are indicated in boldface. The consensus sequences of the conserved inverted sequences are given below the aligned sequences. The start codons of the cutB genes are underlined. Abbreviations: JC1, Mycobacterium sp. strain JC1; JLS, Mycobacterium sp. strain JLS; KMS, Mycobacterium sp. strain KMS; MCS, Mycobacterium sp. strain MCS; Msm, M. smegmatis; Mtb, M. tuberculosis H37Rv; BCG, M. bovis BCG; Mbo, M. bovis; Mma, M. marinum; Mul, M. ulcerans.
