Methionine-mediated gene expression and characterization of the CmhR regulon in Streptococcus pneumoniae

(Submitter supplied) In this study, we investigated the transcriptomic response of Streptococcus pneumoniae D39 to methionine. Transcriptome comparison of the S. pneumoniae D39 wild-type grown in chemically defined medium (CDM) with 0mM to 10mM methionine revealed the elevated expression of various genes/operons involved in methionine synthesis and transport (fhs, folD, gshT, metA, metB, metEF, metQ, tcyB, spd-0150, spd-0431, and spd-0618). more...

Sialic acid-mediated gene expression in Streptococcus pneumoniae and the role of NanR as a transcriptional activator of the nan gene cluster

(Submitter supplied) In this study, we investigated the transcriptomic response of Streptococcus pneumoniae D39 to sialic acid (N-acetylneuraminic acid: Neu5Ac). Transcriptome comparison of the D39 wild-type grown in M17 medium with and without sialic acid revealed the elevated expression of various genes and operons including the nan gene cluster (nan operon-I and nanA gene). Our microarray analysis and promoter-lacZ fusion studies showed that the transcriptional regulator NanR acts as a transcriptional activator of nan operon-I and the nanA gene in the presence of sialic acid. more...

GalR Acts as a Transcriptional Activator of galKT in the Presence of Galactose in Streptococcus pneumoniae

(Submitter supplied) We explored the regulatory mechanism of Leloir pathway genes in Streptococcus pneumoniae D39. Here, we demonstrate that the expression of galKT is galactose dependent. By microarray analysis and quantitative RT-PCR, we further show the role of the transcriptional regulator GalR, present upstream of galKT, as a transcriptional activator of galKT in the presence of galactose. Moreover, we predict a 19-bp regulatory site (5'-GATAGTTTAGTAAAATTTT-3' ) for the transcriptional regulator GalR in the promoter region of galK, which is also highly conserved in other streptococci. more...

The regulation of the AdcR regulon in Streptococcus pneumoniae depends both on Zn2+- and Ni2+- availability

(Submitter supplied) By using the transcriptomic approach, we have elucidated the effect of Ni2+ on the global gene expression of S. pneumoniae D39 by identifying several differentially expressed genes/operons in the presence of a high extracellular concentration of Ni2+. The genes belonging to the AdcR regulon (adcRCBA, adcAII-phtD, phtA, phtB and phtE) and the PsaR regulon (pcpA, prtA and psaBCA) were highly upregulated in the presence of Ni2+. more...

Fucose-mediated transcriptional activation of the fcs operon by FcsR in Streptococcus pneumoniae

(Submitter supplied) In this study, we explore the impact of fucose on the transcriptome of S. pneumoniae D39. The expression of various genes and operons, including the fucose uptake PTS and utilization operon (fcs operon), was altered in the presence of fucose. By means of quantitative RT-PCR and β-galactosidase analysis, we demonstrate the role of the transcriptional regulator FcsR, present upstream of the fcs operon, as a transcriptional activator of the fcs operon. more...
