Fracturing Rings to Understand Lantibiotics
Chemistry & Biology, 2008 Haloduracin is a bacterially produced antibiotic system of two alkali-stable peptides (Halalpha and Halbeta) that have extensive posttranslational modifications, including lanthionine rings. Now, Cooper et al. (2008) revise the structure of Halbeta and demonstrate that some of the lanthionine rings are not essential for bioactivity.

Lantibiotics as prospective antimycobacterial agents [PDF]
Bioengineered Bugs, 2010 Mycobacteria contribute substantially to human infectious disease, most notably the primary pathogens of tuberculosis (TB), leprosy and Bureli ulcer. Global prospects for TB control are challenged by the emergence of drug-resistant strains. If we are to stay ahead of mycobacterial strains developing resistance to chemotherapeutic regimens, all new ...

Quorum sensing-controlled gene expression in lactic acid bacteria [PDF]
, 1998 Quorum sensing in lactic acid bacteria (LAB) involves peptides that are directly sensed by membrane-located histidine kinases, after which the signal is transmitted to an intracellular response regulator. This regulator in turn activates transcription of

Dysbiosis in the Pathogenesis of Atopic Dermatitis
The Journal of Dermatology, Volume 53, Issue 3, Page 388-398, March 2026.ABSTRACT Atopic dermatitis (AD) is a chronic inflammatory skin disease characterized by epidermal barrier dysfunction and immune dysregulation. Recent research highlights cutaneous dysbiosis as a critical factor in its pathogenesis. In this review, we summarize the interplay between the skin microbiota and host immunity, contrasting the homeostatic ...
