Altering the Structure of Carbohydrate Storage Granules in the Cyanobacterium Synechocystis sp. Strain PCC 6803 through Branching-Enzyme Truncations.
UNLABELLED Carbohydrate storage is an important element of metabolism in cyanobacteria and in the chloroplasts of plants. Understanding how to manipulate the metabolism and storage of carbohydrate is also an important factor toward harnessing cyanobacteria for energy production. While most cyanobacteria produce glycogen, some have been found to accumulate polysaccharides in the form of water-in...

متن کاملThe action of crystalline muscle phosphorylase on outer chains of glycogen and amylopectin.
Degradation of biological macromolecules may take place by one of three enzymatic mechanisms. In the first (single chain), the enzyme remains attached to the substrate until a limit of degradation is reached before a new substrate molecule or unit is attacked. The second mechanism would be a partial or incomplete single chain mechanism. During an encounter between enzyme and substrate, several ...

of polysaccharides are synthesized in plastids by similar enzymes using ADP-glucose as a substrate. The storage polysaccharide is usually defined as a mix of two distinct Alain Bulé on § , Paul Colonna § , and Jack Preiss fractions: amylopectin and amylose. Amylopectin is by *Laboratoire de Chimie Biologique far the major compound. It is of very high molecular Unité Mixte de Recherche NЊ111 du ...
متن کاملToxoplasma gondii Requires Glycogen Phosphorylase for Balancing Amylopectin Storage and for Efficient Production of Brain Cysts
In immunocompromised hosts, latent infection with Toxoplasma gondii can reactivate from tissue cysts, leading to encephalitis. A characteristic of T. gondii bradyzoites in tissue cysts is the presence of amylopectin granules. The regulatory mechanisms and role of amylopectin accumulation in this organism are not fully understood. The T. gondii genome encodes a putative glycogen phosphorylase (T...
