Human fur gene encodes a yeast KEX2-like endoprotease that cleaves pro-beta-NGF in vivo. [PDF]

open access: yes, 1990
Extracts from BSC-40 cells infected with vaccinia recombinants expressing either the yeast KEX2 prohormone endoprotease or a human structural homologue (fur gene product) contained an elevated level of a membrane-associated endoproteolytic activity that ...

Positional scanning and computational modeling reveal determinants of legumain transpeptidase activity

open access: yesProtein Science, Volume 35, Issue 5, May 2026.
Abstract Legumain is a lysosomal cysteine protease that plays a central role in antigen processing for MHC class II presentation. Beyond its canonical proteolytic activity, legumain can also function as a peptide ligase or transpeptidase. This non‐canonical activity becomes particularly relevant under pathophysiological conditions such as cancer and ...

Disrupted Protein Expression and Altered Proteolytic Events in Hypophosphatemic Dentin Can Be Rescued by Dentin Matrix Protein 1

open access: yesFrontiers in Physiology, 2020
Dentin, one of the four mineralized tissues of the craniofacial complex, forms sequentially from the deposition of an organic matrix to the nucleation of an inorganic phase within the matrix scaffold.

Arabidopsis acclimation to daily environmental fluctuations converts a defense response regulator into a susceptibility factor toward Sclerotinia

open access: yesNew Phytologist, Volume 250, Issue 4, Page 2516-2534, May 2026.
Summary Acclimation enables plants to adjust to immediate environmental fluctuations and is therefore key to the resilience of plant disease resistance in a time of climate change. Here, we report on the acclimation of Arabidopsis thaliana quantitative immune responses against the fungal pathogen Sclerotinia sclerotiorum to daily environmental ...

A Physiologically‐Based Quantitative Systems Pharmacology Model of the Incretin Hormones GLP‐1 and GIP and the DPP4 Inhibitor Sitagliptin

open access: yesCPT: Pharmacometrics & Systems Pharmacology, 2020
Incretin hormones glucagon‐like peptide‐1 (GLP‐1) and glucose‐dependent insulinotropic polypeptide (GIP) play a major role in regulation of postprandial glucose and the development of type 2 diabetes mellitus.

Peptide synthesis by recombinant Fasciola hepatica cathepsin L1 [PDF]

open access: yes, 2006
Synthesis of the tripeptide Z-Phe-Arg-SerNH2 has been accomplished by a recombinant cysteine protease, cathepsin L1 from liver fluke (Fasciola hepatica), using Z-Phe-Arg-OMe as acyl acceptor and SerNH2 as nucleophile in 0.1 M ammonium acetate pH 9.0–12.5%

Self‐Adaptive Allantoin@ZIF8 Nanocomposite Hydrogel with Resveratrol Synergy for MRSA‐Infected Wound Regeneration

open access: yesAdvanced Science, Volume 13, Issue 21, 13 April 2026.
Based on allantoin‐loaded ZIF8 nanoparticles (Alla@ZIF8) and methacrylated quaternary ammonium carboxymethyl chitosan/resveratrol composite hydrogels (RMQCC), an adaptive multifunctional hydrogel system (Alla@ZIF8‐Gel) was constructed and confirmed to induce the healing of MRSA‐infected wounds via suppressing bacterial proliferation, alleviating ...

Characterization of a New M13 Metallopeptidase from Deep-Sea Shewanella sp. E525-6 and Mechanistic Insight into Its Catalysis [PDF]

open access: yes, 2016
Bacterial extracellular peptidases are important for bacterial nutrition and organic nitrogen degradation in the ocean. While many peptidases of the M13 family from terrestrial animals and bacteria are studied, there has been no report on M13 peptidases ...

The Brain‐Gut Axis in Parkinson's Disease Pathology

open access: yesComprehensive Physiology, Volume 16, Issue 2, April 2026.
Exposure to environmental toxins induces gut dysbiosis, increases intestinal epithelial barrier permeability, immune activation, and oxidative stress, promoting α‐syn misfolding and propagation. Brainstem DMV neurons exhibit α‐syn pathology, dysregulating neuronal excitability and vagal control of GI functions.
