CONCISE statistical analysis of chemical shifts 10 March 2014

Probability distributionsUnderstanding how the equilibrium among conformational states is altered upon ligand binding, interaction with other binding partners, and/or mutations and post-translational modifications is of critical importance for explaining allosteric signaling in proteins. A paper by Alessandro Cembran et al. describes the CONCISE statistical analysis of chemical shifts, which measures the population shifts and collectiveness of protein response associated with ligand titrations or mutations. At the core of the method is the use of Principal Component Analysis to identify the chemical shift component that is sensitive to the conformational equilibrium and separate it from the noise.

    New book on biological solid-state NMR 6 January 2014

    Fa-An (Frank) ChaoA new book on biological solid-state NMR will soon be available. Published by the Royal Society of Chemistry and edited by Drs. Frances Separovic and Akira Naito it covers the diverse topics in the investigation of membrane active peptides and membrane proteins with an emphasis on employing solid-state NMR. It features a chapter on membrane protein phospholamban, written by the Veglia group.

     



    Frank's Ph. D. defense 17 December 2013

    Fa-An (Frank) ChaoFrank Chao successfully defended his doctoral dissertation titled "On the role of conformational dynamics in enzyme function". Frank has been utilizing solution NMR to probe the dynamics of an artificial enzyme ligase 10C as well as highly evolved protein kinase A.
    Congratulations, Dr. Chao!
