Descripción
The polysaccharide capsule of Streptococcus pneumoniae is the main virulence factor making the bacterium resistant to phagocytosis. The galU gene of Streptococcus pneumoniae encodes a UDP-glucose pyrophosphorylase absolutely required for capsule biosynthesis. In silico analyses indicated that galU gene is co-transcribed with the gpdA gene and four putative promoter regions located upstream gpdA were predicted. One of them behaved as a functional promoter in a promoter reporter system. It is conceivable that the sequence responsible for initiating transcription of gpdA-galU operon is an extended -10 site TATGATA(T/G)AAT. Semiquantitative real-time reverse transcription PCR experiments indicated that galU was expressed mainly in the exponential phase of growth.
