Algal glyceraldehyde-3-phosphate dehydrogenase. Pyridine-nucleotide requirements of two enzymes purified from Scenedesmus obliquus

European Journal of Biochemistry
M J O'Brien, R Powls


Two enzymes with glyceraldehyde-3-phosphate dehydrogenase activity have been purified from heterotrophically grown Scenedesmus obliquus by ion-exchange chromatography and gel filtration. The D-enzyme has a molecular weight of 550000 and a VNADH: VNADPH ratio of 16 whereas the T-enzyme has a molecular weight of 140000 and a VNADH:VNADPH ratio of 0.15. The two enzymes, however, are very similar with regard to their Michaelis constants for the reduced pyridine nucleotides, pH optimum, subunit size and ultraviolet absorption.

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.

Central Pontine Myelinolysis

Central Pontine Myelinolysis is a neurologic disorder caused most frequently by rapid correction of hyponatremia and is characterized by demyelination that affects the central portion of the base of the pons. Here is the latest research on this disease.

Myocardial Stunning

Myocardial stunning is a mechanical dysfunction that persists after reperfusion of previously ischemic tissue in the absence of irreversible damage including myocardial necrosis. Here is the latest research.

Pontocerebellar Hypoplasia

Pontocerebellar hypoplasias are a group of neurodegenerative autosomal recessive disorders with prenatal onset, atrophy or hypoplasia of the cerebellum, hypoplasia of the ventral pons, microcephaly, variable neocortical atrophy and severe mental and motor impairments. Here is the latest research on pontocerebellar hypoplasia.

Cell Atlas Along the Gut-Brain Axis

Profiling cells along the gut-brain axis at the single cell level will provide unique information for each cell type, a three-dimensional map of how cell types work together to form tissues, and insights into how changes in the map underlie health and disease of the GI system and its crosstalk with the brain. Disocver the latest research on single cell analysis of the gut-brain axis here.
