The results of kinetic studies are presented for two forms of soluble 3':5'-AMP-dependent protein kinase, obtained by DEAE-cellulose and hydroxyl apatite chromography. The pH optimum for both forms of the enzyme is shown to be 6.8-7.0; their activity is the highest at ionic strength of 0.023. Both forms of the enzyme at the above values of pH and ionic strength are thermoinactivated by the exponential law, their inactivation rate constants rise with temperature. Calcium ions in a concentration of 1.10(6)-2.10(-3) M have no effect on their activity.

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.
