The 2-[18O]phosphorothioate of D-glycerate, chiral at phosphorus, was prepared. The chiral phosphoryl group was transferred enzymically to ADP [by using enolase and pyruvate kinase (ATP:pyruvate 2-O-phosphotransferase; EC] resulting in the synthesis of adenosine 5'-O-([gamma-18O],gamma-thio)triphosphate. This labeled ATP was used as a thiophosphoryl group donor in the reactions catalyzed by glycerol kinase (ATP:glycerol 3-phosphotransferase; EC and by hexokinase (ATP:D-hexose 6-phosphotransferase; EC The product from the latter (glucose 6-phosphorothioate) was converted enzymically into glycerol phosphorothioate. Determination of the relative configurations and diastereoisomeric purities of the samples of glycerol phosphorothioate demonstrates that all three phosphokinases (pyruvate kinase, glycerol kinase, and hexokinase) transfer the thiophosphoryl group with complete stereospecificity, and further shows that these reactions follow an identical stereochemical course.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Synapse Loss as Therapeutic Target in MS

As we age, the number of synapses present in the human brain starts to decline, but in neurodegenerative diseases this occurs at an accelerated rate. In MS, it has been shown that there is a reduction in synaptic density, which presents a potential target for treatment. Here is the latest research on synapse loss as a therapeutic target in MS.
