Suppression of isotope scrambling in cell-free protein synthesis by broadband inhibition of PLP enymes for selective 15N-labelling and production of perdeuterated proteins in H2O
Suppression of isotope scrambling in cell-free protein synthesis by broadband inhibition of PLP enymes for selective 15N-labelling and production of perdeuterated proteins in H2O
Abstract Selectively isotope labelled protein samples can be prepared in vivo or in vitro from selectively labelled amino acids but, in many cases, metabolic conversions between different amino acids result in isotope scrambling. The best results are obtained by cell-free protein synthesis, where metabolic enzymes are generally less active, but isotope scrambling can never be suppressed completely. We show that...

Cell-free expression and stable isotope labelling strategies for membrane proteins
Cell-free expression and stable isotope labelling strategies for membrane proteins
Abstract Membrane proteins are highly underrepresented in the structural data-base and remain one of the most challenging targets for functional and structural elucidation. Their roles in transport and cellular communication, furthermore, often make over-expression toxic to their host, and their hydrophobicity and structural complexity make isolation and reconstitution a complicated task, especially in cases where proteins are targeted to inclusion bodies. The development of cell-free expression systems...

Dear All,
I have a very basic question for this forum but I am starting only now to work in this field and hope you will understand it.
I am currently starting the process of purchasing a fully equipped NMR device and because of that I am trying to get involved all valuable manufactures on the market.
As far as my knowledge goes I have focused my attention on:
-Bruker
-Varian
