The atom simultaneously joins neighboring chains to form an infinite layer. The average distances Nd-O and Nd-N are 2.45 and 2.74 I. An attempt to determine the coordinates of the hydrogen atoms was unsuccessful.doi:10.1007/BF00747514M. S. Khiyalov...
Key bilins and corresponding linker proteins in the EET pathways based on the shortest bilin distances are shown as dots and cartoon diagrams, respectively. Each bilin’s 10th C atom (the central carbon between the rings B and C of the bilin) is shown as a dot. Dots are colored according...
The Sec61/SecY channel allows the translocation of many proteins across the eukaryotic endoplasmic reticulum membrane or the prokaryotic plasma membrane. In bacteria, most secretory proteins are transported post-translationally through the SecY channel by the SecA ATPase. How a polypeptide is moved thr...
Refinement of X-ray single-crystal and neutron powder data shows that Mn2P2O7, a 6.633(1), b 8.584(1), c 4.546(1) A, beta 102.67(1)o, space group C2/m, Z = 2, has the same crystal structure as thortveitite but there is a positional disorder of the bridging O atom giving ...

Chitobiose was build in YASARA, forcefield parameters were assigned using the AutoSMILES approach [44], in a first step YASARA calculated semi-empirical AM1 Mulliken point charges that were corrected by assignment of AM1BCC atom types and improved AM1BCC charges by fragments of molecules with...
Environmental sex reversal (ESR) is the change of the sex of an individual from male to female or female to male at a specific time in the environment. Creatures with sex reversal mainly have both male and female reproductive organs in their bodies, usually expressing only one, and at a la...
A crystal structure determination of one example, [Fe(3-MeO-salen)(5-Ph-imd)(H2O)]BPh4·H 2O, shows that the iron atom is in the plane of the N2O2 donor set with axial distances of Fe-OH2 = 2.205 and Fe-N(imd) = 2.132 . The compound (C51H48BFeN4O5) crystallizes in the ...
Carbapenems are antibiotics of last resort in the clinic. Owing to their potency and broad-spectrum activity, they are an important part of the antibiotic arsenal. The vital role of carbapenems is exemplified by the approval acquired by Merck from the US
