CcpA Mediates the Catabolite Repression of tst in Staphylococcus aureus [PDF]
Infection and Immunity, 2008 ABSTRACT Some clinical isolates of Staphylococcus aureus produce the superantigenic toxic shock syndrome toxin 1 (TSST-1), encoded by tst , located on pathogenicity islands. The expression of tst is complex and is influenced by environmental conditions such ...

Frontiers in Microbiology, 2018 Fructooligosaccharides (FOSs) metabolism in Lactobacillus plantarum is controlled by two gene clusters, and the global regulator catabolite control protein A (CcpA) may be involved in the regulation. To understand the mechanism, this study focused on the

Microorganisms, 2021 Carbon catabolite repression (CCR) is a common mechanism pathogenic bacteria use to link central metabolism with virulence factor synthesis. In gram-positive bacteria, catabolite control protein A (CcpA) and the histidine-containing phosphocarrier ...

Verification of CcpA gene knockout
, 2021 To verify whether the CcpA gene was successfully deleted, we designed the primer for PCR. The primer was designed across the upstream and downstream sequences of the CcpA gene, with a size of about 1827bp. Results showed that two (1827bp and 1985bp) PCR products (WT2 and KO2) were produced, then the amplified DNA products of WT2 and KO2 were ...

CcpA and CodY Coordinate Acetate Metabolism in Streptococcus mutans [PDF]
Applied and Environmental Microbiology, 2017 ABSTRACT In the dental caries pathogen Streptococcus mutans , phosphotransacetylase (Pta) and acetate kinase (Ack) convert pyruvate into acetate with the concomitant generation of ATP. The genes for this pathway are tightly regulated by multiple environmental and intracellular inputs, but the basis for ...

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.The continuous, but obviously geometrically limited Mg↔Zn substitution in members of the two basic structures types of intermetallics, the KHg2‐type dizincides, and the MgZn2/Laves‐type dimagnesidesof Ca, Sr, and Ba exhibit a large phase widths for CaMg2 only. Instead, the larger alkaline‐earth elements form the “optimized” complex compounds A11Mg16Zn6

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 ...

Frontiers in Bioengineering and Biotechnology, 2021 Carbon catabolite repression (CCR) limits microbial utilization of lignocellulose-derived pentoses. To relieve CCR in Clostridium beijerinckii NCIMB 8052, we sought to downregulate catabolite control protein A (CcpA) using the M1GS ribozyme technology. A

Do Tech‐Based New Ventures Founded During Major Economic Crises Generate Different R&D Outputs?
Journal of Product Innovation Management, EarlyView.ABSTRACT Tech‐based ventures—regardless of external circumstances—must allocate resources to research and development (R&D) activities to satisfy their raison d'être and establish their market positioning. When founded during economic crises, these ventures encounter distinctive opportunities but also face resource scarcity, both of which significantly
