Catalysis and allostery in bacterial ATP phosphoribosyltransferases

The FEBS Journal, EarlyView.
ATP phosphoribosyltransferase (ATPPRT) catalyses the first reaction of L‐histidine biosynthesis. L‐Histidine allosterically inhibits ATPPRT to regulate this energy‐intensive pathway in histidine‐synthesising organisms, such as bacteria, archaea and plants.

A guide to host genetic determinants of female microbiome composition across distinct anatomical niches

The FEBS Journal, EarlyView.
Host genetic variation in immune regulation and cell signalling genes was associated with microbiome composition across vaginal, gut, oral and skin sites, while associations involving metabolic function, epithelial barrier integrity and hormonal processes were more site‐specific. Overall, our findings indicate that host genetic variation contributes to

Distinct Microbial and Host Proteome Signatures Relate to Proteolytic Activity in Gingival Crevicular Fluid in an Exploratory Study of Patients With Periodontitis

Journal of Clinical Periodontology, EarlyView.
ABSTRACT Aim Risk assessment tools for periodontitis lack sufficient precision to predict disease progression. The aim of this exploratory study was to evaluate proteolytic activity (PA) in gingival crevicular fluid in relation to clinically assessed progression risk, microbial community composition and host proteome. Materials and Methods Samples were

Hidradenitis suppurativa skin microbiome: In‐depth analysis and modulation by systemic therapies

Journal of the European Academy of Dermatology and Venereology, EarlyView.
Hidradenitis suppurativa skin exhibits profound dysbiosis, characterized by the depletion of homeostatic commensals and expansion of anaerobic pathogens. Longitudinal evaluation reveals that while systemic antibiotics successfully reverse HS dysbiosis, biologics (adalimumab and secukinumab) fail to clear pathogens despite clinical healing.

Beta-lactam resistance in Campylobacter [PDF]

, 2011
Resistance to β-lactam antibiotics in Campylobacter is often associated with the production of a β-lactamase; to date the genomically encoded bla\(_{OXA-61}\) and the closely related cj0299 are the only described β-lactamase genes of Campylobacter ...
