A Novel Regulator of Activation-Induced Cytidine Deaminase/APOBECs in Immunity and Cancer: Schrödinger’s CATalytic Pocket

open access: yesFrontiers in Immunology, 2017
Activation-induced cytidine deaminase (AID) and its relative APOBEC3 cytidine deaminases boost immune response by mutating immune or viral genes. Because of their genome-mutating activities, AID/APOBECs are also drivers of tumorigenesis.

MAMMALIAN METHYLMALONYL ISOMERASE AND VITAMIN B(12) COENZYMES.

open access: yesProceedings of the National Academy of Sciences of the United States of America, 1960
In 1955 Flavin et al.1-4 found that the main pathway of propionic acid oxidation in animal tissues proceeds via the reaction sequence propionate ATPC propionyl CoA5 ATPCOYmethylmalonyl CoA -succinyl CoA succinate.

The binding of oxidized coenzymes by glutamate dehydrogenase and the effects of glutarate and purine nucleotides.

open access: yesBiochemical Journal, 1972
1. The binding of NAD(+) and NADP(+) to glutamate dehydrogenase has been studied in sodium phosphate buffer, pH7.0, by equilibrium dialysis. Approximate values for the dissociation constants are 0.47 and 2.5mm respectively.

Comparison of tissue preparation methods for assay of nicotinamide coenzymes.

open access: yesPlant Physiology, 1987
To prepare tissues for analysis of NAD(+), NADH, NADP(+), and NADPH, common practice is to freeze samples in liquid nitrogen, often followed by freeze-drying, before extraction in HCl or NaOH. With cucumber (Cucumis sativus L.) cotyledons, prefreezing in

The Role of Single-Nucleotide Polymorphisms in the Function of Candidate Tumor Suppressor ALDH1L1

open access: yesFrontiers in Genetics, 2019
Folate (vitamin B9) is a common name for a group of coenzymes that function as carriers of chemical moieties called one-carbon groups in numerous biochemical reactions. The combination of these folate-dependent reactions constitutes one-carbon metabolism,
