Nucleotides: Structure and Properties [PDF]

open access: yes, 2005
Nucleotides consist of a nitrogen-containing base, a five-carbon sugar, and one or more phosphate groups. Cells contain many types of nucleotides, which play a central role in a wide variety of cellular processes, including metabolic regulation and the ...

Protein engineering of oxidoreductases utilizing nicotinamide-based coenzymes, with applications in synthetic biology

open access: yesSynthetic and Systems Biotechnology, 2017
Two natural nicotinamide-based coenzymes (NAD and NADP) are indispensably required by the vast majority of oxidoreductases for catabolism and anabolism, respectively.

Synthetic Biomimetic Coenzymes and Alcohol Dehydrogenases for Asymmetric Catalysis

open access: yesCatalysts, 2019
Redox reactions catalyzed by highly selective nicotinamide-dependent oxidoreductases are rising to prominence in industry. The cost of nicotinamide adenine dinucleotide coenzymes has led to the use of well-established elaborate regeneration systems and ...

Whole Blood Metabolomics by 1H NMR Spectroscopy Provides a New Opportunity To Evaluate Coenzymes and Antioxidants.

open access: yesAnalytical Chemistry, 2017
Conventional human blood metabolomics employs serum or plasma and provides a wealth of metabolic information therein. However, this approach lacks the ability to measure and evaluate important metabolites such as coenzymes and antioxidants that are ...

Atherosclerosis and Coenzyme Q10 [PDF]

open access: yesInternational Journal of Molecular Sciences, 2019
Atherosclerosis is the most common cause of cardiac deaths worldwide. Classically, atherosclerosis has been explained as a simple arterial lipid deposition with concomitant loss of vascular elasticity. Eventually, this condition can lead to consequent blood flow reduction through the affected vessel.

Effects of Cholecalciferol on Key Components of Vitamin D-Endo/Para/Autocrine System in Experimental Type 1 Diabetes

open access: yesInternational Journal of Endocrinology, 2018
Objectives. Recent prospective studies have found the associations between type 1 diabetes (T1D) and vitamin D deficiency. We investigated the role of vitamin D in the regulation of 25OHD-1α-hydroxylase (CYP27B1) and VDR expression in different tissues ...

Isolation of an Enzyme-Coenzyme A Intermediate from Succinyl Coenzyme A-Acetoacetate Coenzyme A Transferase [PDF]

open access: yesJournal of Biological Chemistry, 1967
Abstract An alkali-labile enzyme-coenzyme A intermediate has been isolated by molecular exclusion chromatography of succinyl-CoA-acetoacetate coenzyme A transferase after incubation with acetoacetyl-CoA or succinyl-CoA. Treatment of the intermediate with tritium-labeled sodium borohydride results in enzyme inactivation and incorporation of ...
