Journal of Biological Chemistry, 2002 Because of the apparently greater conformational flexibility of yeast versus muscle actin and the ability of other members in the actin protein superfamily to efficiently use both ATP and GTP, we assessed the ability of yeast actin to function with GTP.

The chloroplast import receptor Toc34 functions as preprotein-regulated GTPase [PDF]
, 2002 Toc34 is a protein of the chloroplast outer envelope membrane that acts as receptor for preproteins containing a transit sequence. The recognition of preproteins by Toc34 is regulated by GTP binding and phosphorylation.

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 ...

GTP: Gatekeeper for Autophagy [PDF]
Molecular Cell, 2010 Chaperone-mediated autophagy (CMA) is involved in cellular quality control, and in the response to stress, deterioration in CMA contributes to the aging phenotype and to various disorders. The paper by Bandyopadhyay et al. in this issue of Molecular Cell demonstrates the role of GTP binding by elongation factor 1 alpha (EF1alpha) in regulating the ...

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 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 ...
