Investigating the Role of Conformational Flexibility in tRNA Aminoacylation
… to a catalytic site, or release products. The energetic contribution of protein flexibility to catalysis is not well understood, despite numerous high resolution crystal structures available for numerous proteins bound with their corresponding ligands.

Conformational Entropy in PEPCK Catalysis: Dynamic Motions Critical to Function
… free energy balance, meaning the lid pays an energetic penalty to close, which is offset by the energetic contribution from substrate binding. To investigate the role of the loop, specifically the open/closed transition, and to probe for unappreciated roles, multiple mutant enzymes were …

Smallmouth Bass Seasonal Dynamics in Northeastern South Dakota Glacial Lakes
… prey items. For the final objective, bioenergetics simulations were conducted on data collected from May to October 1994 at Lake Oahe in two locations (Oahe Dam and Okobojo Bay) and from May to September 2008 in Pickerel Lake. Bioenergetics models were constructed for age-1 to -3 …

Coupled deformation-diffusion-fracture theories for solids : application to polymeric gels and hydrogen embrittlement in steels
… entirely entropic in nature, there is also an energetic contribution from the deformation of the backbone bonds in a chain and/or the crosslinks. It is this energetic part of the free energy that drives the progressive damage and fracture of polymeric materials. We have implemented our theory …

Investigating the photosynthesis of Symbiodinium in Caribbean gorgonian corals
… a potential fitness cost to branches, as the energetic contribution of their Symbiodinium may be reduced at elevated temperature. Understanding the symbioses between gorgonian corals and Symbiodinium and how they respond to elevated temperature will aid in understanding why gorgonian corals …

Ions in Water: Free Energies, Surface Effects, and Geometrical Constraints.
… (unless this is too small). (ii) The entropic contribution is the same order of magnitude as the energetic contribution, and therefore cannot be neglected for quantitative results. (iii) A pure energetic analysis can give a qualitative description of the ion position at room temperature. (iv) …

Structural requirements for enzymatic efficiency in cofactor-independent decarboxylation
… I have determined intrinsic binding energy (IBE) contributions of these residues. Using a similar analysis with mutants of remote residues that selectively form hydrogen bonding (T159V, R203A and Y206F) and hydrophobic (V182A) interactions in Ec, I have determined the energetic contribution of …

Investigating the influence of dietary fiber source and multicarbohydrase supplementation on digestibility, energy, systemic health, water balance, and gut motility in gestating sows
… multicarbohydrase supplementation increased the energetic contribution of IF and SF in sow diets and may reduce systemic endotoxin and inflammatory pressures throughout gestation, but mechanisms are unique to dietary fiber type.

Diet and Body Composition of Migrating Lesser Scaup (Aythya affinis) in Eastern South Dakota
… generally represented a low proportion of total energetic contribution. In earlier studies (1980s), the frequency of occurrence of amphipods in scaup diets was noted at 51% (Afton et al. 1991). In this study (2000s), amphipods were found in 33% of scaup diets. Conversely, chironomids were …

Productivity and Trophic Interactions in the Missouri River Impoundments
… gizzard shad abundance, distribution, and their contribution to the growth dynamics of walleyes in Lake Oahe are poorly understood. In addition to the trophic interactions of walleye and gizzard shad, similarities/differences between foraging patterns of walleye and sauger Sander canadenses, two …
