The MerR‐family regulator NmlR is involved in the defense against oxidative stress in Streptococcus pneumoniae

Molecular Microbiology, Volume 119, Issue 2, Page 191-207, February 2023., 2023
In this work, we have studied the transcriptome of Streptococcus pneumoniae under HOCl stress and characterized the MerR family regulator NmlR as HOCl‐sensing transcriptional activator of the alcohol dehydrogenase‐encoding adhC gene. NmlR was oxidized by HOCl to intersubunit disulfides and S‐glutathionylated in vitro, resulting in transcriptional ...

Transcriptome, Phenotypic, and Virulence Analysis of Streptococcus sanguinis SK36 Wild Type and Its CcpA-Null Derivative (ΔCcpA)

Frontiers in Cellular and Infection Microbiology, 2019
Catabolic control protein (CcpA) is linked to complex carbohydrate utilization and virulence factor in many bacteria species, influences the transcription of target genes by many mechanisms.

High- and low-affinity cre boxes for CcpA binding in Bacillus subtilis revealed by genome-wide analysis

BMC Genomics, 2012
Background In Bacillus subtilis and its relatives carbon catabolite control, a mechanism enabling to reach maximal efficiency of carbon and energy sources metabolism, is achieved by the global regulator CcpA (carbon catabolite protein A).

Transcriptome Analysis Reveals Catabolite Control Protein A Regulatory Mechanisms Underlying Glucose-Excess or -Limited Conditions in a Ruminal Bacterium, Streptococcus bovis

Frontiers in Microbiology, 2021
Ruminants may suffer from rumen acidosis when fed with high-concentrate diets due to the higher proliferation and overproduction of lactate by Streptococcus bovis.

Regulation of CcpA on the growth and organic acid production characteristics of ruminal Streptococcus bovis at different pH

BMC Microbiology, 2021
Background Catabolite control protein A (CcpA) regulates the transcription of lactate dehydrogenase and pyruvate formate-lyase in Streptococcus bovis, but knowledge of its role in response to different pH is still limited.

luxS contributes to intramacrophage survival of Streptococcus agalactiae by positively affecting the expression of fruRKI operon

Veterinary Research, 2023
The LuxS quorum sensing system is a widespread system employed by many bacteria for cell-to-cell communication. The luxS gene has been demonstrated to play a crucial role in intramacrophage survival of piscine Streptococcus agalactiae, but the underlying

Functional analysis of the role of CcpA in Lactobacillus plantarum grown on fructooligosaccharides or glucose: a transcriptomic perspective

Microbial Cell Factories, 2018
Background The catabolite control protein A (CcpA) is a master regulator of many important cellular processes in Gram-positive bacteria. In Lactobacillus plantarum, CcpA directly or indirectly controls the transcription of a large number of genes that ...

Effect of a glucose impulse on the CcpA regulon in Staphylococcus aureus

BMC Microbiology, 2009
Background The catabolite control protein A (CcpA) is a member of the LacI/GalR family of transcriptional regulators controlling carbon-metabolism pathways in low-GC Gram-positive bacteria.

Effects of ccpA gene deficiency in Lactobacillus delbrueckii subsp. bulgaricus under aerobic conditions as assessed by proteomic analysis

Microbial Cell Factories, 2020
Background Aerobic growth provides benefits in biomass yield and stress tolerance of Lactobacillus delbrueckii subsp. bulgaricus (L. bulgaricus). Catabolite control protein A (CcpA) is a master regulator involved in the aerobic and anaerobic growth ...
