DOI: 10.1021/acs.biochem.8b00574
Abstract: In photosystem II (PSII), redox-active tyrosine Z (TyrZ) forms a low-barrier H-bond with Nε of D1-His190. The PSII crystal structures show that Nδ of D1-His190 donates an H-bond to the carbonyl O of D1-Asn298. However,… read more here.

DOI: 10.1021/acs.orglett.3c00143
Abstract: The visible-light-induced photoredox carbon radical formation from aqueous sulfoxonium ylides has been demonstrated for the first time. While direct reduction of sulfoxonium ylides by H2O efficiently generates the corresponding hydrocarbon compounds, the use of additional… read more here.
