Assay for GTP Cyclohydrolase II Activity in Bacterial Extracts

Bio-Protocol, 2014
Riboflavin is the precursor of flavin nucleotides FMN and FAD, they play significant roles in all organisms. GTP is the initial precursor on riboflavin biosynthesis pathway and GTP cyclohydrolase II catalyzes the first step of this pathway.

Retraction Note: Receptor tyrosine kinase inhibitor Sunitinib and integrin antagonist peptide HM-3 show similar lipid raft dependent biphasic regulation of tumor angiogenesis and metastasis

Journal of Experimental & Clinical Cancer Research, 2020
The authors have retracted this article [1] because the bands shown in Fig. 5 panel D for GTP-RhoA/Control, GTP-RhoA/Sunitinib (2 and 64 nM) and GTP-RhoA/HM-3 (4.5 and 72 uM) are not data generated as part of this study.

Pyruvate kinase directly generates GTP in glycolysis, supporting growth and contributing to guanosine toxicity

mBio
Guanosine triphosphate (GTP) is essential for macromolecular biosynthesis, and its intracellular levels are tightly regulated in bacteria. Loss of the alarmone (p)ppGpp disrupts GTP regulation in Bacillus subtilis, causing cell death in the presence of ...

Uncoupling of dynamin polymerization and GTPase activity revealed by the conformation-specific nanobody dynab

eLife, 2017
Dynamin is a large GTPase that forms a helical collar at the neck of endocytic pits, and catalyzes membrane fission (Schmid and Frolov, 2011; Ferguson and De Camilli, 2012).
