The effect of temperature change on the kinetic behaviour of yeast phosphofructokinase

Abstract

Yeast phosphofructokinase does not exhibit any cold sensitivity. The kinetic properties of the enzyme have been investigated in the range between 10 degrees C and 30 degrees C in dependence on fructose 6-phosphate and ATP. Although a significant increase in the enzyme activity with rising temperature does not occur, the shape of the ATP velocity curves is not markedly altered. With increasing concentrations of fructose-6-phosphate the efficiency of temperature on the catalytic process increases, indicating a small temperature effect on the shape of the fructose-6-phosphate velocity curves. The results are interpreted in terms of an adequate kinetic model.

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.

Archaeal RNA Polymerase

Archaeal RNA polymerases are most similar to eukaryotic RNA polymerase II but require the support of only two archaeal general transcription factors, TBP (TATA-box binding protein) and TFB (archaeal homologue of the eukaryotic general transcription factor TFIIB) to initiate basal transcription. Here is the latest research on archaeal RNA polymerases.
