Chitotriazolan (poly(β(1-4)-2-(1H-1,2,3-triazol-1-yl)-2-deoxy-d-glucose)) derivatives: Synthesis, characterization, and evaluation of antibacterial activity

Rathinam, Sankar; Hjálmarsdóttir, Martha Ásdís; Thygesen, Mikkel B.; Másson, Már (Elsevier B.V., 2021-09-01)

Here we describe the first synthesis of a new type of polysaccharides derived from chitosan. In these structures, the 2-amino group on the pyranose ring was quantitively replaced by an aromatic 1,2,3-triazole moiety. The 2-amino group of chitosan and ...
QM/MM calculations reveal a bridging hydroxo group in a vanadium nitrogenase crystal structure

Benediktsson, Bardi; Þórhallsson, Albert Þ.; Bjornsson, Ragnar (Royal Society of Chemistry (RSC), 2018)

A new 1.2 Å crystal structure of vanadium nitrogenase, isolated under turnover conditions, recently revealed a light atom ligand (OH or NH) replacing the bridging S2B sulfide of the FeV cofactor. QM/MM calculations on the new structure now reveal the ...
