mBio, 2017 Copper (Cu) ions serve as catalytic cofactors to drive key biochemical processes, and yet Cu levels that exceed cellular homeostatic control capacity are toxic. The underlying mechanisms for Cu toxicity are poorly understood.

The SVP–FRO6 Module Integrates the Control of Leaf Senescence and Flowering in Arabidopsis
Plant, Cell &Environment, Volume 49, Issue 9, Page 7191-7209, September 2026.ABSTRACT Plants coordinate major developmental transitions by integrating intrinsic genetic programs with environmental signals, where nutrient availability serves as a critical external factor shaping growth and fitness. Iron (Fe), an essential micronutrient for cellular respiration and photosynthesis, is strictly regulated through sophisticated ...

ChemBioChem, Volume 27, Issue 16, 27 August 2026.Approved zinc‐binding drugs and newly synthesized HisPyr ligands were evaluated as adjuvants to meropenem against metallo‐β‐lactamase‐producing Klebsiella pneumoniae. Chlorpropamide and D‐penicillamine restored meropenem activity against the VIM‐1‐producing strain, while computational analyses supported interactions with the enzyme's binuclear zinc ...

The essential nutrient elements in photosynthesis
Frontiers in PhotobiologyEssential plant nutrient elements are “eaten” along with light in the process of photosynthesis, primarily in the leaves. Two pigment-protein systems embedded in the thylakoid membrane, Photosystem I and Photosystem II, mediate light absorption ...

Bioavailability of Metal Ions and Evolutionary Adaptation
Life, 2012 The evolution of life on earth has been a long process that began nearly 3,5 x 109 years ago. In their initial moments, evolution was mainly influenced by anaerobic environments; with the rise of O2 and the corresponding change in bioavailability of ...

Probing metalloproteins by voltammetry
, 2006 Dynamic electrochemical methods, which have long held an important place among the techniques of the coordination chemist, have generally remained unexploited by those seeking to understand the complex and often elusive chemistry of metal centres in proteins.
