Path to Flavinylation
Flavin-containing cofactors play an important role in many enzymatic biochemical reactions that involve electron and/or group transfer. In some, but not all flavin-containing enzymes, the cofactor is covalently bound. This is not a trivial distinction, because covalent binding alters the redox potential of the flavin, a change frequently required… Read MoreFeb. 26, 2018

Targeting Topoisomerase II Inhibitors
Targeting Topoisomerase II Inhibitors Topoisomerases are critical enzymes during DNA replication and transcription, as they are responsible for untangling the knots and twists that can form as DNA is unwound and rewound during these processes. Type II topoisomerases accomplish this task by making a temporary double stranded break… Read MoreFeb. 26, 2018

Mitochondrial mutations and disease
Mitochondria are cellular organelles with their own DNA. Their role in power generation makes them susceptible to oxidative damage, including the formation of DNA-damaging chemical complexes called adducts. While one such adduct, M1dG, is normally excised by cells from the genomic DNA, mitochondria apparently lack this repair mechanism. This month in… Read MoreFeb. 22, 2018

Focus on Mitochondrial DNA Damage
Focus on Mitochondrial DNA Damage DNA damage occurs constantly as a result of physical and chemical insults. Such insults include direct oxidation of the DNA or attack by reactive species generated by the oxidation of lipids. These reactions produce many forms of damage, among them an exocyclic adduct of… Read MoreFeb. 22, 2018

Linking Cell Differentiation, Death, and Mitochondrial Function
Linking Cell Differentiation, Death, and Mitochondrial Function We are only now beginning to understand the complex regulatory processes that control the differentiation of pluripotent stem cells (PSCs), and we know even less about how the differentiation process alters the structure and function of cellular organelles. Of particular interest in… Read MoreFeb. 15, 2018
