The pH dependence of polymerization and bundling by the essential bacterial cytoskeltal protein FtsZ [PDF]

, 2011
There is a growing body of evidence that bacterial cell division is an intricate coordinated process of comparable complexity to that seen in eukaryotic cells.

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.

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 ...

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 ...

Generation of specific antibodies against the rap1A, rap1B and rap2 small GTP-binding proteins. Analysis of rap and ras proteins in membranes from mammalian cells [PDF]

, 1992
Specific antibodies against rap1A and rap1B small GTP-binding proteins were generated by immunization of rabbits with peptides derived from the C-terminus of the processed proteins.

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.

Ectopic A-lattice seams destabilize microtubules [PDF]

, 2014
Natural microtubules typically include one A-lattice seam within an otherwise helically symmetric B-lattice tube. It is currently unclear how A-lattice seams influence microtubule dynamic instability.

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.

The activation mechanism of Irga6, an interferon-inducible GTPase contributing to mouse resistance against Toxoplasma gondii [PDF]

, 2011
Background: The interferon-inducible immunity-related GTPases (IRG proteins/p47 GTPases) are a distinctive family of GTPases that function as powerful cell-autonomous resistance factors.
