Domain movements in protein kinases

Current Opinion in Structural Biology, 1994
Structural studies of the catalytic subunit of the cAMP-dependent protein kinase, both by crystallographic methods and in solution, reveal two conformations. Crystal structures of several other protein kinases have also been solved in the past year. With this combined information we can begin to define mobile domains and subdomains within the conserved

Influence of Heterologous Tobamovirus Movement Protein and Chimeric-Movement Protein Genes on Cell-to-Cell and Long-Distance Movement

Virology, 1994
Sunn-hemp mosaic tobamovirus (SHMV) moves slowly from cell to cell in Nicotiana tabacum cv. Xanthi, but fails to move long distance. To determine the role of the SHMV movement protein (MP) in cell-to-cell and long-distance movement in tobacco, the SHMV MP gene was inserted into a TMV-cDNA clone that had approximately the 5'-half of the endogenous MP ...

Specificity of Bipartite Geminivirus Movement Proteins

Virology, 1993
Pseudorecombinants produced by exchanging genome components (DNAs A and B) of the geminiviruses African cassava mosaic virus (ACMV) and Indian cassava mosaic virus (ICMV), ACMV, and tomato golden mosaic virus (TGMV), and TGMV and abutilon mosaic virus (AbMV) are not infectious in their common host Nicotiana benthamiana.

Structural Mechanisms for Domain Movements in Proteins

Biochemistry, 1994
We survey all the known instances of domain movements in proteins for which there is crystallographic evidence for the movement. We explain these domain movements in terms of the repertoire of low-energy conformation changes that are known to occur in proteins.

Role of Plant Virus Movement Proteins

2008
Plant viruses spread from the initially infected cells to the rest of the plant in several distinct stages. First, the virus (in the form of virions or nucleic acid protein complexes) moves intracellularly from the sites of replication to plasmodesmata (PD, plant-specific intercellular membranous channels), the virus then transverses the PD to spread ...

Fluorescent protein recruitment assay for demonstration and analysis of in vivo protein interactions in plant cells and its application to Tobacco mosaic virus movement protein.

The Plant Journal, 2010
We describe a simple fluorescent protein-based method to investigate interactions with a viral movement protein in living cells that relies on the in vivo re-localization of proteins in the presence of their interaction partners.

Movement of the position of the transition state in protein folding

Biochemistry, 1995
Hammond behavior, in which two neighboring states move closer to each other along the reaction coordinate as the energy difference between them becomes smaller, has previously been observed for the transition state of unfolding of barnase. Here, we report Hammond behavior for the small protein chymotrypsin inhibitor 2 (CI2), which folds and unfolds via

Implication of the C terminus of the Prunus necrotic ringspot virus movement protein in cell-to-cell transport and in its interaction with the coat protein.

Journal of General Virology, 2010
The movement protein (MP) of Prunus necrotic ringspot virus (PNRSV) is required for viral transport. Previous analysis with MPs of other members of the family Bromoviridae has shown that the C-terminal part of these MPs plays a critical role in the ...

Beyond movement: expanding functional landscape of luteovirus movement proteins

Trends in Plant Science
Viruses explore the potential multifunctional capacity of the proteins encoded in their compact genome to establish infection. P4 of luteoviruses has emerged as one such multifunctional protein. Expressed from an open reading frame (ORF) nested within coat protein ORF, it displays diverse subcellular localizations and interactions, reflecting its ...

Movement Profiles: A Tool for Quantitative Analysis of Cell-to-Cell Movement of Plant Viral Movement Proteins

2008
Movement proteins (MPs) are virally encoded factors that mediate transport of viral nucleic acid between plant cells. Many MPs are able to move between cells themselves. This feature serves as the basis for evaluation of the transport activity of individual MPs.
