Activity Gel Analysis of Endopeptidases in Rose Petals

Horticultural Plant Journal, 2016
Poor resolution for the identification of endopeptidase (EP) activity in activity gel assays is a critical issue in the analysis of the postharvest physiology of rose petals. In this paper, major factors influencing EP activity gel assays were evaluated.

Presence and expression of hydrogenase specific C-terminal endopeptidases in cyanobacteria [PDF]

, 2003
BACKGROUND: Hydrogenases catalyze the simplest of all chemical reactions: the reduction of protons to molecular hydrogen or vice versa. Cyanobacteria can express an uptake, a bidirectional or both NiFe-hydrogenases.

The role of lipid metabolism in neuronal senescence

FEBS Open Bio, EarlyView.
Disrupted lipid metabolism, through alterations in lipid species or lipid droplet accumulation, can drive neuronal senescence. However, lipid dyshomeostasis can also occur alongside neuronal senescence, further amplifying tissue damage. Delineating how lipid‐induced senescence emerges in neurons and glial cells, and how it contributes to ageing and ...

Safety evaluation of the food enzyme papain, a cysteine endopeptidase complex from the latex of <i>Carica papaya</i> L. [PDF]

EFSA J
Abstract The food enzyme is a cysteine endopeptidase complex, containing papain (EC 3.4.22.2), chymopapain (EC 3.4.22.6), caricain (EC 3.4.22.30) and glycyl endopeptidase (EC 3.4.22.25), obtained from the latex of unripe Carica papaya L. by Enzybel International SA. It is intended to be used in nine food manufacturing processes.

Identification of Fibrinolytic Activity in Iranian Vipera Lebetina Venom

Journal of Mazandaran University of Medical Sciences, 2020
Background and purpose: Vipera lebetina lives in different areas in Iran, and its venom contains a variety of proteins with coagulant and anticoagulant activities. Fibrinolytic enzymes could have a therapeutic role in dissolution of blood clots, so, this

Metallopeptidases of Toxoplasma gondii: in silico identification and gene expression

Parasite, 2018
Metallopeptidases are a family of proteins with domains that remain highly conserved throughout evolution. These hydrolases require divalent metal cation(s) to activate the water molecule in order to carry out their catalytic action on peptide bonds by ...

Bioinspired Bromination Enables Extensible, Strain‐Stiffening Resilin Peptide Scaffolds with Tunable Degradation

Advanced Functional Materials, EarlyView.
Bioinspired bromination of a resilin‐derived peptide enables the fabrication of electrospun nanofibrous scaffolds that uniquely combine strain‐stiffening elasticity, proteolytic stability, and antioxidant functionality. These brominated peptide–gelatin hybrids mimic the extensibility of natural elastomers, demonstrating tunable mechanical resilience ...
