Chelatins in Euglena gracilis and Ochromonas danica

Comparative Biochemistry and Physiology. C, Comparative Pharmacology and Toxicology

Abstract

Amino acid analysis was performed on low molecular weight copper binding proteins purified from two species of Protozoa after exposure to a high level of this metal. The compound from Ochromonas is similar to Cu-chelatins. The two peptides from Euglena have a different molecular weight and a very dissimilar amino acid composition. Peptide No. 1 has a peculiar composition with a high content of aspartic acid and arginine. Some speculations are made about its detoxification role in comparison with other compounds found in blue-green algae.

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.

Synthetic Genetic Array Analysis

Synthetic genetic arrays allow the systematic examination of genetic interactions. Here is the latest research focusing on synthetic genetic arrays and their analyses.

Congenital Hyperinsulinism
