Fractional-order susceptible-infected model: definition and applications to the study of COVID-19 main protease [PDF]

open access: yes, 2020
We propose a model for the transmission of perturbations across the amino acids of a protein represented as an interaction network. The dynamics consists of a Susceptible-Infected (SI) model based on the Caputo fractional-order derivative.

Dermatophyte infection: from fungal pathogenicity to host immune responses

open access: yesFrontiers in Immunology, 2023
Dermatophytosis is a common superficial infection caused by dermatophytes, a group of pathogenic keratinophilic fungi. Apart from invasion against skin barrier, host immune responses to dermatophytes could also lead to pathologic inflammation and tissue ...

Human CLPP reverts the longevity phenotype of a fungal ClpP deletion strain [PDF]

open access: yes, 2013
Mitochondrial maintenance crucially depends on the quality control of proteins by various chaperones, proteases and repair enzymes. While most of the involved components have been studied in some detail, little is known on the biological role of the ...

Protease inhibitors targeting the main protease and papain-like protease of coronaviruses [PDF]

open access: yesExpert Opinion on Therapeutic Patents, 2020
The two cysteine proteases from the coronaviruses, which produced deadly outbreaks in the last two decades, SARS CoV-1/2, and MERS, the main protease (Mpro) and the papain-like protease (PLP) are conserved among the three pathogens and started to be considered as exciting drug targets for developing antivirals.We review the drug design landscape in the

Insights into AMS/PCAT transporters from biochemical and structural characterization of a double Glycine motif protease

open access: yeseLife, 2019
The secretion of peptides and proteins is essential for survival and ecological adaptation of bacteria. Dual-functional ATP-binding cassette transporters export antimicrobial or quorum signaling peptides in Gram-positive bacteria.

Rapid enzymatic test for phenotypic HIV protease drug resistance [PDF]

open access: yes, 2003
A phenotypic resistance test based on recombinant expression of the active HIV protease in E. coli from patient blood samples was developed. The protease is purified in a rapid onestep procedure as active enzyme and tested for inhibition by five selected

Vitamin D: Proteases, protease inhibitors and cancer [PDF]

open access: yesCell Cycle, 2010
The active vitamin D metabolite 1alpha,25-dihydroxyvitamin D(3) (1,25(OH)(2)D(3), Calcitriol) is a major regulator of gene expression in higher organisms. Protein abundance is an endpoint of gene expression that results from the balance between induction and degradation and is essential for adequate cell function.

Identification of a Novel Thermostable Alkaline Protease from Bacillus megaterium-TK1 for the Detergent and Leather Industry

open access: yesBiology, 2020
An increased need by the green industry for enzymes that can be exploited for eco-friendly industrial applications led us to isolate and identify a unique protease obtained from a proteolytic Bacillus megaterium-TK1 strain from a seawater source.

Site-specific identification and quantitation of endogenous SUMO modifications under native conditions. [PDF]

open access: yes, 2017
Small ubiquitin-like modifier (SUMO) modification regulates numerous cellular processes. Unlike ubiquitin, detection of endogenous SUMOylated proteins is limited by the lack of naturally occurring protease sites in the C-terminal tail of SUMO proteins ...

IgA1 protease

open access: yesThe International Journal of Biochemistry & Cell Biology, 2006
IgA1 proteases are proteolytic enzymes that cleave specific peptide bonds in the human immunoglobulin A1 (IgA1) hinge region sequence. Several species of pathogenic bacteria secrete IgA1 proteases at mucosal sites of infection to destroy the structure and function of human IgA1 thereby eliminating an important aspect of host defence. IgA1 proteases are
