Mechanisms governing bacterial capsular polysaccharide attachment and chain length

open access: yesAnnals of the New York Academy of Sciences, Volume 1548, Issue 1, Page 80-98, June 2025.
Abstract Capsular polysaccharides (CPSs) are high‐molecular weight glycopolymers that form a capsule layer on the surface of many bacterial species. This layer serves as a crucial barrier between bacteria and their environment, protecting them from host immune responses and environmental stressors while facilitating adaptation to host niches.

The Lactobacillus plantarum ftsH gene is a novel member of the CtsR stress response regulon [PDF]

open access: yes, 2008
FtsH proteins have dual chaperone-protease activities and are involved in protein quality control under stress conditions. Although the functional role of FtsH proteins has been clearly established, the regulatory mechanisms controlling ftsH expression ...

Citrate Supplementation Modulates Medium Viscosity and Poly‐γ‐Glutamic Acid Synthesis by Engineered B. subtilis 168

open access: yesEngineering in Life Sciences, Volume 25, Issue 3, March 2025.
ABSTRACT The industrially attractive biopolymer poly‐γ‐glutamic acid (γ‐PGA) is commonly produced by species of the genus Bacillus by co‐feeding different carbon‐ and nitrogen‐sources. Recent studies have highlighted the pivotal role of co‐metabolization of a rapidly degradable carbon source such as glycerol together with citrate for γ‐PGA production ...

Vancomycin‐intermediate Staphylococcus aureus employs CcpA‐GlmS metabolism regulatory cascade to resist vancomycin

open access: yesMedComm – Future Medicine, Volume 3, Issue 4, December 2024.
The metabolic alteration in vancomycin‐intermediate Staphylococcus aureus (VISA) is associated with ccpA upregulation. WalKR and GraSR TCSs control the expression of CcpA, which orchestrates GlmS to form a CcpA‐GlmS cascade to drive carbon and nitrogen flow for the biosynthesis of cell wall precursor in VISA.

Production‐optimized fermentation of antifungal compounds by Bacillus velezensis LZN01 and transcriptome analysis

open access: yesMicrobial Biotechnology, Volume 17, Issue 10, October 2024.
The yields of antimicrobial compounds, such as surfactin, fengycin, shikimic acid, and myriocin, increased or were observed in the optimized fermentation CFS. In conclusion, fermentation conditions improved the antifungal activity of the LZN01 strain and influenced the expression of genes involved in the synthesis of antimicrobial compounds.

Understanding Staphylococcus aureus in hyperglycaemia: A review of virulence factor and metabolic adaptations

open access: yesWound Repair and Regeneration, Volume 32, Issue 5, Page 661-670, September/October 2024.
Abstract Staphylococcus aureus is one of the most commonly detected bacteria in diabetic skin and soft tissue infections. The incidence and severity of skin and soft tissue infections are higher in patients with diabetes, indicating a potentiating mechanism of hyperglycaemia and infection.

Cloning and expression of the ccpA gene encoding catabolite control protein from Thermoactinomyces sp. E79

open access: yes, 2000
The gene ccpA encoding the catabolite control protein A (CcpA) of Thermoactinomyces sp. E79 has been cloned and characterized. Nucleotide sequence analysis of the CcpA clone showed that the cloned fragment contained the full structural gene for a protein

Effect of the catabolic control protein A of Lactiplantibacillus plantarum AR113 on its colonization in vivo

open access: yesFood Frontiers, Volume 5, Issue 4, Page 1796-1805, July 2024.
Abstract Lactiplantibacillus plantarum is selective for carbohydrate utilization, which is primarily regulated by the catabolic control protein A (ccpA). To investigate the impact of carbohydrate metabolism on the in vivo colonization of L. plantarum AR113, we constructed a ccpA knockout strain (AR113ΔccpA). In vitro assays showed that AR113ΔccpA had a

Fight or flee, a vital choice for Clostridioides difficile

open access: yesmLife, Volume 3, Issue 1, Page 14-20, March 2024.
Abstract Clostridioides difficile is a leading cause of healthcare‐associated infections, causing billions of economic losses every year. Its symptoms range from mild diarrhea to life‐threatening damage to the colon. Transmission and recurrence of C. difficile infection (CDI) are mediated by the metabolically dormant spores, while the virulence of C ...
