Mechanistic Enzymology of Soluble Methane Monooxygenase. Enzyme catalysis is the increase in the rate of a process by a biological molecule, an "enzyme".Most enzymes are proteins, and most such processes are chemical reactions. Here, we demonstrate that upon lipopolysaccharide (LPS) stimulation, macrophages shift from producing ATP by oxidative phosphorylation to glycolys … Ph.D. Programs Biochemistry, Cellular and Molecular Biology. Dan Sutherlin- Vice President of Small Molecule Discovery Chemistry at Genentech. Nitrification is an important step in the nitrogen cycle in soil. The transformation of ammonia to nitrite is usually the rate limiting step of nitrification. In eukaryotic cells, mechanistic repair of DSBs occurs primarily by two pathways: Non-Homologous End-Joining (NHEJ) and Homology Directed Repair (HDR). Haldane, a physiologist, resisted reduction of biological phenomena to mechanistic explanations, as he saw the structure of biological organisms and their action being disanalogous to what was seen in physical systems. Similar to the physiological fixation of N 2, the reduction of CO to hydrocarbons also has its equivalence in industrial chemistry, in the form of the 1925 Fischer-Tropsch process (15).

Edited by Chris Whitman. Cancer cells from a primary tumor can disseminate to other tissues, remaining dormant and clinically undetectable for many years. The Department of Biochemistry's weekly BCH 252 seminar series is presented this week by Dr. James Stivers, Professor, Johns Hopkins University Seminar Title: “A tale of a tail: A role for disorder in DNA damage recognition” Bio: Dr. Stivers has over 25 years of accumulated expertise in enzymology, high-throughput screening,… The Journal of Biological Chemistry welcomes high-quality science that seeks to elucidate the molecular and cellular basis of biological processes. Activated macrophages undergo metabolic reprogramming, which drives their pro-inflammatory phenotype, but the mechanistic basis for this remains obscure.

Mechanistic study on antibacterial action of zinc oxide nanoparticles synthesized using green route. Here, we report the structure of a two CO-bound state of V nitrogenase at 1.05 Å resolution, with one μ-bridging and one terminal CO molecule. This additional, specific ligand binding site suggests a mechanistic route for CO reduction and hydrocarbon formation, as well as a second access pathway for protons required during the reaction.
