Specificity of the HIV-1 Protease on Substrates Representing the Cleavage Site in the Proximal Zinc-Finger of HIV-1 Nucleocapsid Protein

open access: yesViruses, 2021
To explore the sequence context-dependent nature of the human immunodeficiency virus type 1 (HIV-1) protease’s specificity and to provide a rationale for viral mutagenesis to study the potential role of the nucleocapsid (NC) processing in HIV-1 ...

Tomato marchitez virus, a new plant picorna-like virus from tomato related to tomato torrado virus [PDF]

open access: yes, 2008
A new virus was isolated from a tomato plant from the state of Sinaloa in Mexico. This plant showed symptoms locally known as `marchitez disease¿: severe leaf necrosis, beginning at the base of the leaflets, and necrotic rings on the fruits.

Viruses and viral proteins

open access: yesIUCrJ, 2014
For more than 30 years X-ray crystallography has been by far the most powerful approach for determining the structures of viruses and viral proteins at atomic resolution.

Coagulation, Protease-Activated Receptors, and Viral Myocarditis [PDF]

open access: yesJournal of Cardiovascular Translational Research, 2013
The coagulation protease cascade plays an essential role in hemostasis. In addition, a clot contributes to host defense by limiting the spread of pathogens. Coagulation proteases induce intracellular signaling by cleavage of cell surface receptors called protease-activated receptors (PARs).

Comparative analysis between a low pathogenic and a high pathogenic influenza H5 hemagglutinin in cell entry

open access: yesVirology Journal, 2009
Avian influenza viruses continue to threaten globally with pandemic potential. The first step in a potential pandemic is the ability of the virus to enter human cells which is mediated by the viral surface glycoprotein hemagglutinin (HA).

Camostat mesylate inhibits SARS-CoV-2 activation by TMPRSS2-related proteases and its metabolite GBPA exerts antiviral activity

open access: yesEBioMedicine, 2021
Background Antivirals are needed to combat the COVID-19 pandemic, which is caused by SARS-CoV-2. The clinically-proven protease inhibitor Camostat mesylate inhibits SARS-CoV-2 infection by blocking the virus-activating host cell protease TMPRSS2. However,

The role of proteases in the invasion of SARS-CoV-2 virus into human host cells

open access: yesJournal of Current Biomedical Reports, 2021
The new coronavirus, which originally broke out in Wuhan, China, in December 2019, increase quickly around the world, causing a pandemic all over the world. The virus uses its spike protein to enter the human host cells.

Targeting SARS-CoV-2 Proteases for COVID-19 Antiviral Development

open access: yesFrontiers in Chemistry, 2022
The emergence of severe acute respiratory syndrome (SARS-CoV-2) in 2019 marked the third occurrence of a highly pathogenic coronavirus in the human population since 2003.

Characterising proteolysis during SARS-CoV-2 infection identifies viral cleavage sites and cellular targets with therapeutic potential

open access: yesNature Communications, 2021
During SARS-CoV-2 replication, viral and cellular proteases play crucial roles and have been shown to be promising anti-viral targets. Here, Meyer et al.
