Abstract

Phosphate and pyrophosphate increased the rate of reduction of adrenodoxin by NADPH-adrenodoxin reductase and NADPH, pyrophosphate being one order more effective than the former. However, the cytochrome c reduction by the electron transport system was inhibited in the presence of inorganic (pyro)phosphate. On the other hand, ADP and ATP enhanced the rates of reduction of both adrenodoxin and cytochrome c through adrenodoxin by the electron transport system. GTP also enhanced the rate of reduction of cytochrome c by this system, whereas AMP showed no appreciable enhancement. These inorganic and nucleotide phosphates did not affect the rate of ferricyanide reduction by the reductase.

COVID-19

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.

Genetic Screens in iPSC-derived Brain Cells

Genetic screening is a critical tool that can be employed to define and understand gene function and interaction. This feed focuses on genetic screens conducted using induced pluripotent stem cell (iPSC)-derived brain cells. It also follows CRISPR-Cas9 approaches to generating genetic mutants as a means of understanding the effect of genetics on phenotype.
