Germinal proto-mitochondria from rat liver
Biochemistry and Biophysics Reports, 2019 A number of properties of the smallest (less than 0.2 μm) germinal proto-mitochondria (PRMC) from rat liver have been studied. These PRMC were obtained by filtering the light fraction of hepatic mitochondria (MC) through calibrated millipore membranes ...

Activation of a Flavoprotein by Proteolysis
Journal of Biological Chemistry, 1989 Chymotryptic digestion of brain pyridoxine-5-P oxidase brings about a 4-fold enhancement of the catalytic power (Vmax/KM) using pyridoxine-5-P as substrate in the assay mixtures. The chymotrypsin-treated enzyme is less susceptible to inhibition by pyridoxal-5-P than the native enzyme.

Structures and mechanism of the monoamine oxidase family
Biomolecular Concepts, 2011 Members of the monoamine oxidase family of flavoproteins catalyze the oxidation of primary and secondary amines, polyamines, amino acids, and methylated lysine side chains in proteins.

Investigation of real-time photorepair activity on DNA via surface plasmon resonance.
PLoS ONE, 2012 The cyclobutane pyrimidine dimer (CPD) and 6-4 lesion formations along with the specific breaks on strands are the most common type of DNA damage caused by Ultraviolet light (UV) irradiation.

Engineering an Artificial Flavoprotein Magnetosensor [PDF]
Journal of the American Chemical Society, 2016 Migratory birds use the Earth's magnetic field as a source of navigational information. This light-dependent magnetic compass is thought to be mediated by cryptochrome proteins in the retina. Upon light activation, electron transfer between the flavin adenine dinucleotide cofactor and tryptophan residues leads to the formation of a spin-correlated ...

MoleculesRiboflavin analogs lacking one methyl group (7α or 8α) can still serve as a surrogate for riboflavin in riboflavin-deficient microorganisms or animals. The absence of both methyl groups at once completely abolishes this substitution capability.

Two-photon microscopy for non-invasive, quantitative monitoring of stem cell differentiation. [PDF]
PLoS ONE, 2010 The engineering of functional tissues is a complex multi-stage process, the success of which depends on the careful control of culture conditions and ultimately tissue maturation.

Mechanisms of flavoprotein‐catalyzed reactions [PDF]
European Journal of Biochemistry, 1989 Flavoproteins are a class of enzymes catalyzing a very broad spectrum of redox processes by different chemical mechanisms. This review describes the best studied of these mechanisms and discusses factors possibly governing reactivity and specificity.

FEBS Open Bio, EarlyView.This study investigated a novel WST‐8‐based assay for evaluating d‐Amino acid oxidase (DAO) inhibitors. We confirmed its effectiveness using known inhibitors and found that uremic toxins possess relatively weak inhibitory activity compared to existing drugs.

FEBS Open Bio, EarlyView.Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...
