Experimental Evidence for a Metal‐Related Function of a Cyanobactin
Angewandte Chemie International Edition, Volume 65, Issue 25, 15 June 2026.Cyanobactins such as patellamides are produced by cyanobacteria profusely and have been studied extensively, but almost exclusively for their cytotoxic properties. Discussed is unprecedented experimental evidence for a metal‐related biological function – likely CO2 transport from the ascidian to the cyanobacterial symbiont.

Racemisation of Amino Acids: From Synthetic Challenge to Biological Significance
ChemBioChem, Volume 27, Issue 11, 15 June 2026.Racemisation, once considered an undesirable synthetic side reaction, also occurs naturally in amino acids and influences biological processes. Evidence links stereochemical conversion to ageing, protein turnover, and cellular development. This review examines mechanisms, control strategies in synthesis, applications and implications in physiology ...

Beta-lactamases from Yersinia enterocolitica
, 1975 Two beta-lactamases, A and B, have been shown to be present in a strain of Yersinia enterocolitica (w222). Beta-Lactamase A hydrolyses a variety of penicillins and cephalosporins. This enzyme is sensitive to thiol reagents, is only partially inhibited by

Metal‐Dependent Effects and Crowding Robustness of Pseudomonas fluorescens Esterase I
ChemBioChem, Volume 27, Issue 11, 15 June 2026.Pseudomonas fluorescens esterase I retains catalytic activity in metal‐rich and crowded environments, despite metal‐specific inhibitory effects. These findings highlight its robustness for biocatalytic applications in complex environments. Industrial biocatalysts are strongly influenced by their physicochemical environment, yet systematic studies on ...

Primers for Use in Detecting Beta-Lactamases
, 2001 Oliognucleotide primers are provided that are specific for nucleic acid characteristic of certain beta-lactamases. The primers can be employed in methods to identify nucleic acid characteristic of family-specific beta-lactamase enzymes in samples, and ...

Veterinary Record, Volume 198, Issue 12, Page e521-e532, 13–27 June 2026.Abstract Background A structured, behavioural science approach was adopted to develop antimicrobial stewardship interventions in UK first‐opinion companion animal veterinary practice. The objectives were to identify behavioural targets for intervention and to understand how practice contexts influence these behaviours.

British Journal of Clinical Pharmacology, Volume 92, Issue 6, Page 1833-1844, June 2026.Aims Amoxicillin, a widely used β‐lactam antibiotic, requires improved pharmacokinetic characterization during breastfeeding. This study used a population pharmacokinetic (PopPK) approach to model amoxicillin concentrations in breast milk, identify variability sources and estimate infant exposure, applying worst‐case scenarios.
