Ultrafast MAS Solid-State NMR Permits Extensive C-13 and H-1 Detection in Paramagnetic Metalloproteins

David Lyndon Emsley, Moreno Lelli

We show here that by combining tailored approaches based on ultrafast (60 kHz) MAS on the Co-II-replaced catalytic domain of matrix metalloproteinase 12 (CoMMP-12) we can observe and assign, in a highly paramagnetic protein in the solid state, C-13 and eve ...

On the enzymatic activity of catalase: an iron L-edge X-ray absorption study of the active centre

Majed Chergui

Catalase and methaemoglobin have very similar haem groups, which are both ferric, yet catalase decomposes hydrogen peroxide to water and oxygen very efficiently, while methaemoglobin does not. Structural studies have attributed this behaviour to their diff ...
