Lipid-based nanocarriers for oral delivery of peptides☆

open access: yesOilseeds and fats, crops and lipids, 2022
Therapeutic peptides can treat a wide variety of diseases with selective and potent action. Their oral bioavailability is strongly limited by an important proteolytic activity in the intestinal lumen and poor permeation across the intestinal border.

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.

Urine peptidomic biomarkers for diagnosis of patients with systematic lupus erythematosus [PDF]

open access: yes, 2018
Background: Systematic lupus erythematosus (SLE) is characterized with various complications which can cause serious organ damage in the human body. Despite the significant improvements in disease management of SLE patients, the non-invasive diagnosis ...

Effect of Heat Treatment on Protein Self-Digestion in Ruminants’ Milk

open access: yesFoods, 2023
This study investigated whether heat treatments (raw, 63 °C for 30 min, and 85 °C for 5 min) affect protein hydrolysis by endogenous enzymes in the milk of ruminants (bovine, ovine, and caprine) using a self-digestion model.

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

In silico prediction of mutant HIV-1 proteases cleaving a target sequence

open access: yes, 2014
HIV-1 protease represents an appealing system for directed enzyme re-design, since it has various different endogenous targets, a relatively simple structure and it is well studied.

Differential in vitro and in vivo effect of barley cysteine and serine protease inhibitors on phytopathogenic microorganisms [PDF]

open access: yes, 2011
Protease inhibitors from plants have been involved in defence mechanisms against pests and pathogens. Phytocystatins and trypsin/α-amylase inhibitors are two of the best characterized protease inhibitor families in plants.

Influência da ação das enzimas alcalase e flavourzyme no grau de hidrólise das proteínas de carne de frango Influence of alcalase and flavourzyme performance on the degree of hydrolysis of the proteins of chicken meat

open access: yesQuímica Nova, 2009
To study the action of Alcalase and Flavourzyme on the proteins of chicken meat, the influence of the substrate concentration [S], enzyme concentration [E] and hydrolysis time on the degree of hydrolysis (DH) of the proteins was evaluated. The highest DH

Convergent dynamics in the protease enzymatic superfamily

open access: yes, 2006
Proteases regulate various aspects of the life cycle in all organisms by cleaving specific peptide bonds. Their action is so central for biochemical processes that at least 2% of any known genome encodes for proteolytic enzymes.

Cleavage of endogenous gamma ENaC and elevated abundance of alpha ENaC are associated with increased Na+ transport in response to apical fluid volume expansion in human H441 airway epithelial cells [PDF]

open access: yes, 2011
Using human H441 airway epithelial cells cultured at air–liquid interface (ALI), we have uniquely correlated the functional response to apical fluid volume expansion with the abundance and cleavage of endogenous α- and γENaC proteins in the apical ...
