Dynamics of Microtubule Growth and Catastrophe [PDF]

, 2007
We investigate a simple model of microtubule dynamics in which a microtubule evolves by: (i) attachment of guanosine triphosphate (GTP) to its end at rate lambda, (ii) GTP converting irreversibly to guanosine diphosphate (GDP) at rate 1, and (iii ...

Mitochondria-lysosome contacts regulate mitochondrial fission via Rab7 GTP hydrolysis

Nature, 2018
Both mitochondria and lysosomes are essential for maintaining cellular homeostasis, and dysfunction of both organelles has been observed in multiple diseases.

Inhibitory Effects of Green Tea Polyphenols on Microbial Metabolism of Aromatic Amino Acids in Humans Revealed by Metabolomic Analysis

Metabolites, 2019
The bioactivities and potential health benefits of green tea polyphenols (GTP) have been extensively investigated, but the metabolic impact of chronic GTP intake on humans is not well defined.

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.

Citrate Regulates the Saccharomyces cerevisiae Mitochondrial GDP/GTP Carrier (Ggc1p) by Triggering Unidirectional Transport of GTP

Journal of Fungi, 2022
The yeast mitochondrial transport of GTP and GDP is mediated by Ggc1p, a member of the mitochondrial carrier family. The physiological role of Ggc1p in S.

Interaction between chromium GTP and tubulin. Stereochemistry of GTP binding, GTP hydrolysis, and microtubule stabilization

Journal of Biological Chemistry, 1991
Chromium GTP (CrGTP) has been used to probe the stereochemistry of metal-GTP binding to exchangeable site of tubulin and to examine the fate and role of nucleotide-bound metal ion in GTP hydrolysis associated with microtubule assembly. The absolute stereoconfiguration of the two pairs of diastereomers of beta,gamma-bidentate CrGTP has been determined ...

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 ...

An intermolecular G-quadruplex as the basis for GTP recognition in the class V–GTP aptamer [PDF]

RNA, 2016
Many naturally occurring or artificially created RNAs are capable of binding to guanine or guanine derivatives with high affinity and selectivity. They bind their ligands using very different recognition modes involving a diverse set of hydrogen bonding and stacking interactions.

Clinical Significance of Gamma-Glutamyltranspeptidase Combined with Carbohydrate-Deficient Transferrin for the Assessment of Excessive Alcohol Consumption in Patients with Alcoholic Cirrhosis

Medicines, 2021
Background: This study aimed to compare the diagnostic performance of carbohydrate-deficient transferrin (CDT) and gamma-glutamyltranspeptidase (γ-GTP) to assess the single and combined benefits of these biological markers for the detection of chronic ...

OPA1 disease alleles causing dominant optic atrophy have defects in cardiolipin-stimulated GTP hydrolysis and membrane tubulation [PDF]

, 2010
The dynamin-related GTPase OPA1 is mutated in autosomal dominant optic atrophy (DOA) (Kjer type), an inherited neuropathy of the retinal ganglion cells.
