Generation of hydrogen

Alternative energy production through biomass gasification produces combustible gases, such as carbon monoxide, hydrogen, and methane. These gases can be used for generation of direct heat, electricity, or liquid fuels through the Fischer Tropsch process.

The signaling properties of the gasotransmitter molecule hydrogen sulfide (H2S), which is endogenously generated in plant cells, are mainly observed during persulfidation, a protein post-translational modification (PTM) that affects redox-sensitive cysteine residues. There is growing experimental evidence that H2S in higher plants may function as a mechanism of response to environmental stress conditions.

Many biological C-H activation reactions exhibit nonclassical kinetic isotope effects (KIEs). These nonclassical KIEs are too large (kH/kD 7) and/or exhibit unusual temperature dependence such that the Arrhenius prefactor KIEs (AH/AD) fall outside of the semiclassical range near unity. The focus of this minireview is to discuss such KIEs within the context of the environmentally coupled hydrogen tunneling model.

Theoxidation-promotingreactivityof copper(II) complexof aminoglycosidic antibiotic amikacin [Cu(II)-Ami] in the presence of hydrogen peroxide, was studied at pH 7.4, using 2¢-deoxyguanosine (dG), pBR322 plasmid DNA and yeast tRNA Phe as target molecules. Themixtures of complexwith H2O2were found to be efficient oxidants, converting dG to its 8-oxo derivative, generating strand breaks in plasmid DNA and multiple cleavages in tRNA Phe .

Chorismate synthase is the last enzyme of the common shikimate pathway, which catalyzes theanti-1,4-elimination of the 3-phosphate group and the C-(6proR) hydrogen from 5-enolpyruvylshikimate 3-phosphate (EPSP) to generate chorismate, a precursor for the biosynthesis of aromatic com-pounds.
