It is shown that KaiB flips between two distinct three-dimensional folds, and its rare transition to an active state provides a time delay that is required to match the timing of the oscillator to that of Earth’s rotation.

An ESEEM (electron spin−echo envelope modulation) spectroscopic study employing a series of 2H-labeled alcohols provides direct evidence that small alcohols (methanol and ethanol) ligate to the Mn…

Electron spin echo electron-nuclear double resonance (ESE-ENDOR) experiments performed on a broad radical electron paramagnetic resonance (EPR) signal observed in photosystem II particles depleted of Ca2+ indicate that this signal arises from the redox-active tyrosine YZ, which is proposed to abstracts protons from substrate water bound to the Mn cluster.

The results support a mechanism in which controlled production of O2(•-) by NrdIhq during class Ib RNR cofactor assembly both circumvents the unreactivity of the Mn(II)2 cluster with O2 and satisfies the requirement for an "extra" reducing equivalent in Y(•) generation.
