Enzymes and energy

Ebook "The role of water in ATP hydrolysis energy transduction by protein machinery" introduces recent progress in biological energetics from ATP hydrolysis to molecular machineries. The role of water is now recognized to be essential in biological molecular energetics. Although energetics is a rather distant field to many biologists, any working models for protein machineries such as protein motors, transporters, and other enzymes must be consistent with their energetics.

Biodiesel is a source of renewable energy produced through the transesterification of vegetable oils, animal fats, or the esterification of fatty acids with short chain alcohols such as methanol, ethanol, propanol and butanol in presence of acid catalysts (H2SO4, HCl...), basic catalysts (KOH, NaOH) or biocatalysts (lipase enzymes).

Portland cement is a most popular binder used for soil stabilization. However, the cement remained many drawbacks such as consuming high energy and raw material, releasing huge amount of CO2. The recent study proposed an application of biocement using bacterial enzyme as an alternative binder for stabilizing loose sand soil. A simple method was employed to extract urease enzyme from bacterial cells.

The results of the physiological parameters showed that their profile changes were consistent with those of the proteome analysis. The results of the proteome and physiological parameters showed that K. candel roots could resist highsalinity stress by maintaining a normal Embden-Meyerhof-Parnas and tricarboxylic acid (EMP-TCA) pathway, increasing the activities of various antioxidant enzymes and antioxidant contents, stabilizing the cell wall structure, and accumulating secondary metabolites such as triterpenoids.

Polyhydroxyalkanoate (PHA) is stored as an important carbon and energy source in bacterial cells. For biomedical applications, gram-positive bacteria can be better sources of PHAs, since they lack outer membrane lipopolysaccharide. Although gram-positive Streptomyces coelicolor A3(2) has been indicated as a high potential PHA producer, phaC gene that encodes the key enzyme PHA synthase in the metabolic pathway is not determined in its genome.

In artificial photosynthesis process the photocatalyst-enzyme attached system is a best strategy to utilize solar energy for solar chemical/fuels production. Herein, we prepared a solar light active graphene-based photocatalyst received by the covalent attachment of 9-aminoanthracene (AA) chromophore with chemically converted graphene (CCG) for highly efficient 1,4-NADH regeneration (79.9 %) and conversion of α-ketoglutarate (α-KG) in to Lglutamate (L-GM) (88.3 %) in 2 hrs.

The positive effects of the enzymes are suggested to be due to enhancement of nutrient digestibility in young chicks as well as digestion of soluble and insoluble NSP in corn and SBM. Hence considering the two different experiments on protease and xylanase individually in the Department, the present study was undertaken to utilize xylanase and protease in broilers.

Glyoxalase I (gly I) and Glyoxalase II (gly II), zinc-binding enzymes of the glyoxalase pathway, carry out catabolism of methylglyoxal (MG). Gly II gene cloned from Oryza sativa has been widely used in genetic transformation experiments for salinity tolerance. This study could prove useful in further functional characterization of this important protein.

Dietary starches are important sources of energy for many human societies and it is clear that they can also make quite specific contributions to health. Resistant starch has received much attention for both its potential health benefits (similar to soluble fibre) and functional properties. Resistant starch (RS) encompasses forms of starch, which are not digested in the small intestine by enzymes but fermented in the large intestine.
