TranscriptomicsConditional Essentiality of vicK (walKSpn) Histidine Kinase for Anaerobic Growth of Streptococcus pneumoniae D39
The VicRK two-component system of S. pneumoniae (Pneumococcus) is a member of the essential WalRK (YycFG) family found in low G+C gram positive bacteria. Previously, we showed that phosphorylated VicR response regulator (RR) is essential, because of its strong positive regulation of the pcsB gene, w...

TranscriptomicsIdentification and function of non-coding small RNAs in Streptococcus pneumoniae
We report here an experimental search for small non-coding RNAs in a low GC, gram-positive, human pathogenic bacteria Streptococcus pneumoniae. Based on the bioinformatic analyses by Livny et al. (2006, Nucleic Acids Res. 34:3484-93), we tested 36 candidates by Northern analyses and confirmed the e...

TranscriptomicsCapsule Mediates the Cell Shape of pcsB Mutants in Serotype 2 Streptococcus pneumoniae
PcsB is a protein of unknown function that plays a critical role in cell division in Streptococcus pneumoniae and other ovococcus species of Streptococcus. We constructed isogenic sets of mutants expressing different amounts of PcsB in laboratory strain R6 and virulent serotype 2 strain D39 to evalu...

TranscriptomicsCis- and trans-Regulation of Pneumococcal spxB
Pyruvate oxidase encoded by spxB is a major virulence factor in the human respiratory pathogen Streptococcus pneumoniae. During aerobic growth, SpxB synthesizes large amounts of H2O2 and acetyl phosphate, which can serve as a phosphoryl group donor to response regulators and be converted to ATP. Spx...
