Tyr12 of the finger domain exhibited parallel stacking with the deoxyribose of the incoming dNTP.
In the modeled donor-UGT1A1 complex, the uracil ring of UDPGA interacts with the side chain of R336 and the main chain of L355 and Q357 through hydrogen bonds, and also forms parallel stacking interaction with the indole ring of W354 of the human UGT1A1.
Our focus on Aβ-derived peptides may miss structural contributions like hydrogen-bond ladders, as, for example, for in-parallel stacked Asn or Gln, which also greatly enhances the stability of a parallel orientation.
This is, with increasing supercooling, from a morphology composed essentially of individual lamellae arranged in parallel stacks and radiating from common nuclei through coarse, somewhat branched microstructures whose parallel stacks diverge, to finer, more-branched pseudo-spherulitic textures.
New experimental results for a single coned disk element, the primary parallel stack configuration, and two primary series stack configurations are presented.
Moreover, the parallel pattern also statistically stayed longer, providing more chances for oligomer extending, although the number of parallel stack events was almost equal to antiparallel ones.
The former reaction disrupts the parallel stacking of the chromophores and is reflected as an increase in the ultra-violet spectral intensity.
They are interesting, e.g., for the development of photonic crystals based on parallel stacks of layers of different dielectric constant forming a photonic band gap in a single direction.
