Effect of Green Tea Powder on Physicochemical Properties and Glycemic Potential of Sponge Cake
Journal of Food Quality, 2022 Green tea powder (GTP) is rich in polyphenolic compounds, most particularly catechins. The effects of partial replacement of flour with GTP (10, 20, and 30%) on physicochemical properties, glycemic potential, and sensory attributes were investigated ...

GTP cyclohydrolase I utilizes metal‐free GTP as its substrate [PDF]
European Journal of Biochemistry, 2003 GTP cyclohydrolase I (GCH) is the rate‐limiting enzyme for the synthesis of tetrahydrobiopterin and its activity is important in the regulation of monoamine neurotransmitters such as dopamine, norepinephrine and serotonin. We have studied the action of divalent cations on the enzyme activity of purified recombinant human GCH expressed in Escherichia ...

Mutations in human dynamin block an intermediate stage in coated vesicle formation [PDF]
, 1993 The role of human dynamin in receptor-mediated endocytosis was investigated by transient expression of GTP-binding domain mutants in mammalian cells. Using assays which detect intermediates in coated vesicle formation, the dynamin mutants were found to ...

GTP-Dependent K-Ras Dimerization [PDF]
Structure, 2015 Ras proteins recruit and activate effectors, including Raf, that transmit receptor-initiated signals. Monomeric Ras can bind Raf; however, activation of Raf requires its dimerization. It has been suspected that dimeric Ras may promote dimerization and activation of Raf.

American Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView., 2023 Abstract Dynamin 1 is a GTPase protein involved in synaptic vesicle fission, which facilitates the exocytosis of neurotransmitters necessary for normal signaling. Pathogenic variants in the DNM1 gene are associated with intractable epilepsy, often manifested as infantile spasms at onset, developmental delay, and a movement disorder, and are located in ...

Regulation of local GTP availability controls RAC1 activity and cell invasion
Nature Communications, 2021 Changes in intracellular GTP levels are not considered as a regulatory event in RAC1 activation in live cells since total GTP levels are substantially higher than the RAC1 GTP dissociation constant determined in vitro.
