... is universally mediated by the jaw domain and, in some species, by the additional presence of the Rpo13 subunit. Biochemical and biophysical data, combined with X-ray structures of apo- and DNA-bound a RNAP, have demonstrated the capability of the Rpo13 C-terminus to bind in a sequence-independent manner...

... to equivalent interactions. Thus, using methods available through PISA (Protein Interfaces, Surfaces and Assemblies) [ 18 ], we have analysed the crystal interfaces between the RNAP molecules that form the different crystal lattices. Although the low resolution of all available archaeal RNAP X-ray structures...

...S. Yoshikawa Bovine heart cytochrome c oxidase is a large multi-component membrane protein containing several phospholipids. X-ray structures of this enzyme at high resolution, determined recently, show a trigonal planar structure of Cu B site in the O 2 reduction site, which could contribute...

.... 100 different X-ray structures have been determined ( http://www.mpibp-frankfurt.mpg.de/michel/public/memprotstruct.html ), 18 of them contain tightly bound lipids with assigned head group providing new insight into specific protein–lipid interactions. Lipids are identified in experimental difference...
