Owing to their modular architecture, Cullin-RING ligases allow for specific placement of a large number of substrates in the ubiquitylation zone of the catalytic subunit for efficient poly-ubiquitylation (Fischer et al., 2011; Zimmerman et al., 2010).
We are continuing this work because further optimization needs to be done; we were only able to analyze numerical simulations for a few scenarios with regard to specific placement of feeders corresponding to calculated economic costs.
These will typically include share of shelf and planogram compliance (the specific placement of products on a store shelf).
These results suggest that specific placement of thiophosphates could play an important role in the development of siRNAs as therapeutics by engineering in properties such as strength of binding, nuclease sensitivity, and ultimately efficacy.
Weber, J., Wilke-Mounts, S., Lee, R. S. F., Grell, E. & Senior, A. E. Specific placement of tryptophan in the catalytic sites of Escherichia coli F1-ATPase provides a direct probe of nucleotide binding: maximal ATP hydrolysis occurs with three sites occupied.
Any desired, feasible combination of length and diameter, along with specific placement of hexagonal and pentagonal rings or end caps, can also be controlled.
The denser sampling however allowed testing specific placement of species, showing, for example, that the unusual Australian Plebidonax deltoides is not a member of Donacidae and instead nests within Psammobiidae, suggesting that major revision of Tellinoidea may be required.
In particular, medium to large gaps will likely require microsite specific placement of desired advance regeneration or additional treatments (e.g., vegetation control) to cultivate a dense sapling layer in an acceptable timeframe after harvest.
