Title: The regulation of the AdcR regulon in Streptococcus pneumoniae depends both on Zn2+- and Ni2+- availability      
ID:
PRJNA298223
description:
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+. We have further studied the role of Ni2+ in the regulation of the AdcR regulon by using ICP-MS analysis, electrophoretic mobility shift assays and transcriptional lacZ-reporter studies, and demonstrate that Ni2+ is directly involved in the derepression of the AdcR regulon via the Zn2+-dependent repressor AdcR, and has an opposite effect on the expression of the AdcR regulon as compared to Zn2+. This SuperSeries is composed of the SubSeries listed below. Overall design: Refer to individual Series
