Lanthanide‐Controlled Protein Switches: Development and In Vitro and In Vivo Applications

Angewandte Chemie, Volume 137, Issue 9, February 24, 2025.
Engineering artificial allosteric protein switches controlled by rare earth elements allows the development of assays, construction of bioelectronic devices, and REE‐controlled microorganisms. Abstract Lanthanides, which are part of the rare earth elements group have numerous applications in electronics, medicine and energy storage.

A two-component protease in Methylorubrum extorquens with high activity toward the peptide precursor of the redox cofactor pyrroloquinoline quinone [PDF]

, 2019
Pyrroloquinoline quinone is a prominent redox cofactor in many prokaryotes, produced from a ribosomally synthesized and post-translationally modified peptide PqqA via a pathway comprising four conserved proteins PqqB?E. These four proteins are now fairly

The fox Operon from Rhodobacter Strain SW2 Promotes Phototrophic Fe(II) Oxidation in Rhodobacter capsulatus SB1003 [PDF]

, 2007
Anoxygenic photosynthesis based on Fe(II) is thought to be one of the most ancient forms of metabolism and is hypothesized to represent a transition step in the evolution of oxygenic photosynthesis.
