Spin Dynamics of Flavoproteins

open access: yesInternational Journal of Molecular Sciences, 2023
This short review reports the surprising phenomenon of nuclear hyperpolarization occurring in chemical reactions, which is called CIDNP (chemically induced dynamic nuclear polarization) or photo-CIDNP if the chemical reaction is light-driven. The phenomenon occurs in both liquid and solid-state, and electron transfer systems, often carrying flavins as ...

Oxidation of amines by flavoproteins [PDF]

open access: yesArchives of Biochemistry and Biophysics, 2010
Many flavoproteins catalyze the oxidation of primary and secondary amines, with the transfer of a hydride equivalent from a carbon-nitrogen bond to the flavin cofactor. Most of these amine oxidases can be classified into two structural families, the D-amino acid oxidase/sarcosine oxidase family and the monoamine oxidase family.

NMR of Flavoproteins

2003
Flavoproteins are involved in a wide variety of enzymatic reactions like oxidation, reduction and mono-oxygenation. Consequently, flavin cofactors occur in many different forms including, for example, the oxidized semiquinone and reduced states as well as the C4a-(hydro)peroxyflavin form.

Flavoprotein Kinetics

2003
Flavoproteins are ubiquitous proteins involved in diverse biological processes ranging from redox catalysis and light emission to DNA repair (1). Based on their function, flavoproteins can be divided into several subclasses including electron transferases, photolyases, synthases, dehydrogenases, disulfide reductases, oxidases, and monooxygenases.

Radicals in Flavoproteins

2011
Current technical and methodical advances in electron paramagnetic resonance (EPR) spectroscopy have proven to be very beneficial for studies of stationary and short-lived paramagnetic states in proteins carrying organic cofactors. In particular, the large number of proteins with flavins as prosthetic groups can be examined splendidly by EPR in all its

The acceptor specificity of flavins and flavoproteins. III. Flavoproteins

Biochimica Et Biophysica Acta - Bioenergetics, 1971
Abstract 1. The specificity of flavoproteins towards acceptors has been rather neglected, but an attempt is here made to construct a comparative table of acceptor specificities of those flavoprotein enzymes for which data exist. 2. The acceptor specificity of reduced flavin groups, when combined with apoenzyme proteins, is quite different from that ...
