In order to investigate the effects of salt stress on biochemical and physiological responses of two cultivars of alfalfa (Medicago sativa L.) namely, Diabolourde and Yazdi, chlorophyll content, growth parameters, and proline contents of roots and shoots, reducing sugars contents of roots and shoots, and membrane injuries of the plant samples were subjected to 0, 100, 150, and 200 mM NaCl treat...

The prediction and design at the atomic level of membrane protein structures and interactions is a critical but unsolved challenge. To address this problem, we have developed an all-atom physical model that describes intraprotein and protein-solvent interactions in the membrane environment. We evaluated the ability of the model to recapitulate the energetics and structural specificities of poly...

Computational protein design facilitates the continued development of methods for the design of biomolecular structure, sequence and function. Recent applications include the design of novel protein sequences and structures, proteins incorporating nonbiological components, protein assemblies, soluble variants of membrane proteins, and proteins that modulate membrane function.

Due to the recent increase of natural gas production in the U.S., utilizing natural gas for higher-value chemicals has become imperative. Direct methane aromatization (DMA) is a promising process used to convert methane to benzene, but it is limited by low conversion of methane and rapid catalyst deactivation by coking. Past work has shown that membrane separation of the hydrogen produced in th...
