The unique nucleotide specificity of the sucrose synthase from Thermosynechococcus elongatus
(Elsevier Science, 2013-01)
Sucrose synthase catalyzes the reversible conversion of sucrose and UDP into fructose and UDP-glucose. In filamentous cyanobacteria, the sucrose cleavage direction plays a key physiological function in carbon metabolism, ...
Sucrose in cyanobacteria: From a salt-response molecule to play a key role in nitrogen fixation
(MDPI, 2015-01)
In the biosphere, sucrose is mainly synthesized in oxygenic photosynthetic organisms, such as cyanobacteria, green algae and land plants, as part of the carbon dioxide assimilation pathway. Even though its central position ...
Epidermal growth factor receptor controls glycogen phosphorylase in T cells through small GTPases of the RAS family
(American Society for Biochemistry and Molecular Biology, 2019-03-22)
We recently uncovered a regulatory pathway of the muscle isoform of glycogen phosphorylase (PYGM) that plays an important role in regulating immune function in T cells. Here, using various enzymatic, pulldown, and ...
ADP-glucose pyrophosphorylase: A regulatory enzyme for plant starch synthesis
(Springer, 2004-12)
In plants, the synthesis of starch occurs by utilizing ADP-glucose as the glucosyl donor for the elongation of α-1,4-glucosidic chains. In photosynthetic bacteria the synthesis of glycogen follows a similar pathway. The ...
Understanding the allosteric trigger for the fructose-1,6-bisphosphate regulation of the ADP-glucose pyrophosphorylase from Escherichia coli
(Elsevier France-editions Scientifiques Medicales Elsevier, 2011-10)
ADP-glucose pyrophosphorylase is the enzyme responsible for the regulation of glycogen synthesis in bacteria. The enzyme N-terminal domain has a Rossmann-like fold with three neighbor loops facing the substrate ATP. In the ...
Domain swapping between a cyanobacterial and a plant subunit ADP-glucose pyrophosphorylase
(Oxford University Press, 2006-02)
ADP-glucose pyrophosphorylase (ADP-Glc PPase) catalyzes the regulatory step in the pathway for synthesis of bacterial glycogen and starch in plants. ADP-Glc PPases from cyanobacteria (homotetramer) and from potato (Solanum ...
Biosynthesis of glycogen from uridine diphosphate glucose
(American Chemical Society, 1957)
In vitro synthesis of particulate glycogen
(National Academy of Sciences, 1965-01)
Synthesis of glycogen from uridine diphosphate glucose in liver
(American Society for Biochemistry and Molecular Biology, 1960-04)
ADPglucose pyrophosphorylase's N-terminus: Structural role in allosteric regulation
(Academic Press Inc Elsevier Science, 2006-04)
We studied the functional role of the Escherichia coli ADPglucose pyrophosphorylase's N-terminus in allosteric regulation, and the particular effects caused by its length. Small truncated mutants were designed, and those ...
