Elongin is a heterotrimeric elongation factor for RNA polymerase (Pol) II transcription that is conserved among metazoa. Here, we report three cryo-EM structures of human Elongin bound to transcribing Pol II. The structures show that Elongin subunit ELOA

The structure of a low-potential ferredoxin isolated from Bacillus thermoproteolyticus has been refined by a restrained least-squares method. The final crystallographic R factor is 0.204 for 2906 reflections with F > 3 σ F in the 6.0 to 2.3 Å resolution range. The model contains 81 amino ...
The structure of 1-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide ([C4mpyr][NTf2]) room-temperature ionic liquid at an electrified gold interface was studied using neutron reflectometry, cyclic voltammetry, and differential capacitance measurements. Subtle differences were observed between the...

M.R.Thomsen, ...R.M.NaygaJr., inEncyclopedia of Agriculture and Food Systems, 2014 Nutritional labeling Food labeling became a concern as the food-processing industries were rapidly increasing. The first regulation on food labeling was passed in 1906, and it mainly addressed the issue of food...
We are interested in the problem of predicting secondary structure for small sets of homologous RNAs, by incorporating limited comparative sequence information into an RNA folding model. The Sankoff algorithm for simultaneous RNA folding and alignment is a basis for approaches to this problem. There ...

we explore the growth effect of RD ratio and RD structure with the data of 1998—2009 of the 31 provinces through the panel data model.We find that the RD ratio has a negative effect on economic growth,whereas the basic research and the high school RD investment have positive effect on ...
