A spontaneous mutant of Streptococcus pneumoniae strain D39 exhibiting elevated beta-galactosidase activity was identified. We determined that the beta-galactosidase activity was due to BgaA, a surface protein in S. pneumoniae, and that the expression of bgaA was regulated. Transcription analyses demonstrated expression of bgaA in the constitutive beta-galactosidase (BgaA(C)) mutant, but not in the parent. beta-Galactosidase expression was induced in the parent under specific growth conditions… CONTINUE READING
