Large-Scale Purification of a Stable Form of Recombinant Tobacco Etch Virus Protease

open access: yesBioTechniques, 2001
Tobacco etch virus NIa proteinase (NIa-Pro) has become the enzyme of choice for removing tags and fusion domains from recombinant proteins in vitro. We have designed a mutant NIa-Pro that resists autoproteolytic inactivation and present an efficient ...

RNA packaging and uncoating in simple single-stranded RNA viruses [PDF]

open access: yes, 2012
Simple (non-enveloped) small, positive-sense single-stranded RNA viruses infect hosts from all kingdoms of life. However, their assembly and uncoating processes remain poorly understood. For turnip crinkle virus (TCV), 3D reconstructions by cryoelectron

Mutation of a Short Variable Region in HCpro Protein of Potato virus A Affects Interactions with a Microtubule-Associated Protein and Induces Necrotic Responses in Tobacco

open access: yesMolecular Plant-Microbe Interactions, 2013
Helper component proteinase (HCpro) is a multifunctional protein of potyviruses (genus Potyvirus). HCpro of Potato virus A (PVA) interacts with the microtubule-associated protein HIP2 in host cells, and depletion of HIP2 reduces virus accumulation.

PRODUCTION OF RECOMBINANT, NON-TAGGED PHENYLALANINE AMMONIA-LYASES EMPLOYING TEV PROTEASE-REMOVABLE AFFINITY TAGS

open access: yesStudia Universitatis Babes-Bolyai Chemia, 2022
Nowadays, protein purification by the aid of affinity tags can be carried out with high speed and efficiency. However, in several cases, affinity tags can significantly alter the key properties of enzymes, especially activity and/or thermostability ...

Structural Basis for the Substrate Specificity of Tobacco Etch Virus Protease [PDF]

open access: yesJournal of Biological Chemistry, 2002
Because of its stringent sequence specificity, the 3C-type protease from tobacco etch virus (TEV) is frequently used to remove affinity tags from recombinant proteins. It is unclear, however, exactly how TEV protease recognizes its substrates with such high selectivity.

Viral resistance mediated by shRNA depends on the sequence similarity and mismatched sites between the target sequence and siRNA

open access: yesBiologia Plantarum, 2013
Viral resistance can be effectively induced in transgenic plants through their silencing machinery. Thus, we designed nine short hairpin RNAs (shRNA) constructs to target nuclear inclusion protein b (NIb), helper component proteinase (HC-Pro ...

Development of an assay system for the analysis of host RISC activity in the presence of a potyvirus RNA silencing suppressor, HC-Pro

open access: yesVirology Journal, 2023
Background To investigate the mechanism of RNA silencing suppression, the genetic transformation of viral suppressors of RNA silencing (VSRs) in Arabidopsis integrates ectopic VSR expression at steady state, which overcomes the VSR variations caused by ...

A multidirectional non-cell autonomous control and a genetic interaction restricting tobacco etch virus susceptibility in Arabidopsis. [PDF]

open access: yesPLoS ONE, 2007
Viruses constitute a major class of pathogens that infect a variety of hosts. Understanding the intricacies of signaling during host-virus interactions should aid in designing disease prevention strategies and in understanding mechanistic aspects of host

Convenient Auto-Processing Vector Based on Bamboo Mosaic Virus for Presentation of Antigens Through Enzymatic Coupling

open access: yesFrontiers in Immunology, 2021
We have developed a new binary epitope-presenting CVP platform based on bamboo mosaic virus (BaMV) by using the sortase A (SrtA)-mediated ligation technology. The reconstructed BaMV genome harbors two modifications: 1) a coat protein (CP) with N-terminal

Ultrastructure of the crystalline inclusion induced by tobacco etch virus visualized by freeze-etching

open access: yesJournal of Ultrastructure Research, 1974
Structural subunits of the crystalline inclusion induced by tobacco etch virus were clearly resolved when inclusions were examined both in situ and in isolated preparations by freeze-etch electron microscopy. Data supported the contention that the crystal substructure is organized into laminae and that these laminae assemble into crystals by stacking
