Peroxidases produced by the marine sponge Iotrochota birotulata

1. Two peroxidases, differing in ionic character and substrate specificity, have been isolated from the tropical marine sponge Iotrochota birotulata. 2. Both peroxidases catalyze the oxidation of a number of substrates, and one peroxidase possesses a specificity similar to the terrestrial fungal enzyme chloroperoxidase. 3. Based on inhibition studies utilizing sodium azide, potassium cyanide and 8-hydroxyquinoline, it appears that the peroxidases from I. birotulata are haemoprotein complexes. 4. One peroxidase appears to possess subunit structure, and requires bound divalent metal cations for 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.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Synapse Loss as Therapeutic Target in MS

As we age, the number of synapses present in the human brain starts to decline, but in neurodegenerative diseases this occurs at an accelerated rate. In MS, it has been shown that there is a reduction in synaptic density, which presents a potential target for treatment. Here is the latest research on synapse loss as a therapeutic target in MS.
