Potential Activities of Freshwater Exo- and Endo-Acting Extracellular Peptidases in East Tennessee and the Pocono Mountains

open access: yesFrontiers in Microbiology, 2018
Proteins constitute a particularly bioavailable subset of organic carbon and nitrogen in aquatic environments but must be hydrolyzed by extracellular enzymes prior to being metabolized by microorganisms.

Into the Wild: Farm‐Derived Energy and Nutrients Enter Marine Food Webs With Carrying Capacity Implications for Aquaculture Management

open access: yesReviews in Aquaculture, Volume 18, Issue 3, June 2026.
ABSTRACT Marine aquaculture is expanding globally, yet its interactions with surrounding ecosystems remain complex and insufficiently understood. This study reviews the fluxes of energy and nutrients from three major aquaculture systems: finfish cages, suspended bivalves, and seaweed farms and considers their implications for ecosystem functioning and ...

Spectroscopically Distinct Cobalt(II) Sites in Heterodimetallic Forms of the Aminopeptidase from \u3cem\u3eAeromonas proteolytica\u3c/em\u3e:  Characterization of Substrate Binding [PDF]

open access: yes, 1997
The Co(II)Zn(II)- and Zn(II)Co(II)-substituted derivatives of the aminopeptidase from Aeromonas proteolytica (AAP) were probed by EPR spectroscopy. EPR spectra of the high-spin S = 3/2 Co(II) ions in [CoZn(AAP)] and [ZnCo(AAP)] indicated that each metal ...

Solvent and thermal stability, and pH kinetics, of proline-specific dipeptidyl peptidase IV-like enzyme from bovine serum [PDF]

open access: yes, 2007
Proline-specific dipeptidyl peptidase-like (DPP IV; EC 3.4.14.5) activity in bovine serum has attracted little attention despite its ready availability and the paucity of useful proline-cleaving enzymes.

Nonclassical MHC‐I Molecules: Emerging Therapeutic Targets in Next‐Generation Immunotherapy

open access: yesMedComm, Volume 7, Issue 5, May 2026.
Immunotherapies dependent on classical MHC‐I molecules face significant challenges, including extreme polymorphism and frequent downregulation in pathological conditions. This review discusses how nonclassical MHC‐I molecules (HLA‐E, HLA‐F, HLA‐G, CD1, MR1) may potentially circumvent these limitations through restricted genetic diversity, stable ...

Synergistic Anti-Candida Activity of Bengazole A in the Presence of Bengamide A †. [PDF]

open access: yes, 2019
Bengazoles A⁻G from the marine sponge Jaspis sp. exhibit potent in vitro antifungal activity against Candida spp. and other pathogenic fungi. The mechanism of action (MOA) of bengazole A was explored in Candida albicans under both liquid culture and ...

Advances in Wine Yeast Autolysis: Biochemical and Molecular Mechanisms, and the Release of Organic Compounds in White and Sparkling Wines—An Updated Review

open access: yesComprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 3, May 2026.
ABSTRACT Wine yeasts play a central role in alcoholic fermentation and significantly contribute to the sensory attributes of wines through cellular autolysis during lees aging (sur lie), especially in white wines. This process releases organic compounds that alter the wine's chemical and sensory profile.

A Bifunctional Protease Cleaves the Leader Peptide in the Biosynthesis of Class I Microviridins

open access: yesChemBioChem, Volume 27, Issue 7, 14 April 2026.
Biochemical characterization of the peptidase candidate NosP reveals bifunctional endo‐ and aminopeptidase activity in the leader peptide removal of class I microviridins from Nostoc punctiforme. The discovery of the first leader‐processing peptidase from microviridin biosynthesis may pave the way for the efficient production and bioengineering of ...
