High-affinity PQQ import is widespread in Gram-negative bacteria

Pyrroloquinoline quinone (PQQ) is a soluble redox cofactor used by diverse bacteria. Many Gram-negative bacteria that encode PQQ-dependent enzymes do not produce it and instead obtain it from the environment.

Red blood cell membrane proteome as a reporter of disease severity, transfusion impact and genetic background in transfusion‐dependent β‐thalassaemia

British Journal of Haematology, Volume 208, Issue 6, Page 1980-1992, June 2026.
Summary Omics technologies have transformed research in haemoglobinopathies, yet the proteome of RBCs remains largely unexplored in transfusion‐dependent thalassaemia (TDT). In this proteomic analysis, Red blood cell (RBC) membranes from 48 adults with TDT were compared with healthy controls.

A ‘Genome‐First’ Framework for Next‐Generation Bioinputs: From Functional Mining to Rational Synthetic Microbial Communities

Environmental Microbiology, Volume 28, Issue 5, May 2026.
I propose a ‘genome‐first’ framework to collapse the phenotypic bottleneck in bioinput discovery. By integrating multi‐layered genome mining and reverse ecology, this paradigm enables the rational design of stable synthetic microbial communities for a data‐driven and sustainable agricultural bioeconomy.
