Properties of erythrocyte catalase from heterozygotes for Japanese type acatalasemia

Acta Medica Okayama
M Ogata, J Mizugaki


The level of blood catalase activity in heterozygotes for Japanese type acatalasemia was demonstrated to be about half of normal levels by means of titration and spectrophotometric methods. A distribution plot of catalase activities in heterozygous blood was completely separate from that of normal blood. Comparative analysis of the partially purified erythrocyte catalase preparations obtained from normal and heterozygous individuals revealed no distinct differences between them regarding stability to heat, sodium dodecyl sulfate and some enzyme inhibitors or pH dependency. The erythrocyte catalase in heterozygotes for Japanese type acatalasemia contains about half the normal specific activity and as stable as that in normal individuals.

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.
