Abstract: Photosystem II (PSII) catalyzes the splitting of water, releasing protons and dioxygen. Its highly conserved subunit PsbO extends from the oxygen‐evolving center (OEC) into the thylakoid lumen and stabilizes the catalytic Mn4CaO5 cluster. The high degree… read more here.

DOI: 10.1038/s41598-020-62860-9
Abstract: Anoctamin-1 (ANO1 or TMEM16A) is a homo-dimeric Ca 2+ -activated Cl − channel responsible for essential physiological processes. Each monomer harbours a pore and a Ca 2+ -binding pocket; the voltage-dependent binding of two intracellular… read more here.
