The adc locus, which affects competence for genetic transformation in Streptococcus pneumoniae, encodes an ABC transporter with a putative lipoprotein homologous to a family of streptococcal adhesins.

Abstract excerpt

To identify new components involved in the phenomenon of transformation in Streptococcus pneumoniae, a library of potential mutants has been generated by random insertion of an erythromycin resistance gene. Transformation-deficient mutants were screened using an in situ colony transformation test. The adc locus, which was identified in this search, was cloned and sequenced. Sequence analysis revealed a putative...
