[Change in the active transport of amino acids during competence in Streptococcus pneumoniae].
Streptococcus pneumoniae can be transformed by DNA. Transformation occurs in a transitory physiological state called competence. We observed a modulation of the Vi of aminoacid uptakes which seems selectively related to the energy coupling of the corresponding transports.
