Large, medically important class of proteins starts to yield its secrets Eureka! Science News
Such NMR structure studies were pioneered by Wüthrichand one of the recent innovations has been the use of "microcoils" to enable NMR studies of minute quantities of precious protein samples in solution. Wüthrich's lab, in collaboration with the ...

A new tool to reveal structure of proteins
Eureka! Science News
For roughly a decade, a technique called solid state nuclear magnetic resonance (NMR) spectroscopy has allowed researchers to detect the arrangements of atoms in proteins that defy study by traditional laboratory tools such as X-ray crystallography.

High-yield Escherichia coli-based cell-free expression of human proteins
High-yield Escherichia coli-based cell-free expression of human proteins
Abstract Production of sufficient amounts of human proteins is a frequent bottleneck in structural biology. Here we describe an Escherichia coli-based cell-free system which yields mg-quantities of human proteins in N-terminal fusion constructs with the GB1 domain, which show significantly increased translation efficiency. A newly generated E. coli BL21 (DE3) RIPL-Star strain was used, which contains a variant RNase E with reduced activity and an excess of rare-codon tRNAs, and is devoid of lon and ompT protease...
