The RecA proteins from Mycobacterium tuberculosis and Mycobacterium leprae
contain inteins. In contrast to the M. tuberculosis RecA, the M leprae RecA
is not spliced in Escherichia coli, We demonstrate here that M. leprae Rec
A is functionally spliced in Mycobacterium smegmatis and produces resistanc
e toward DNA-damaging agents and homologous recombination.
