Sequence deletions of 16, 59, and 111 bp as well as a tandem
duplication of 272 bp with respect to the corresponding sequence of
pT48 were identified in the regulatory regions of constitutively expressed ermC genes. Constitutive ermC gene
expression as a consequence of these structural alterations is based on
either the prevention of the formation of mRNA secondary structures in
the translational attenuator or the preferential formation of those
mRNA secondary structures which do not interfere with the translation
of the ermC transcripts. A model for the development of
sequence deletions in the ermC translational attenuator by
homologous recombination is presented and experimentally tested by in
vitro selection of constitutively expressed mutants in staphylococcal
strains deficient and proficient in homologous recombination.
