The effects of alginate lyase treatment on structural characteristics and anti‐photoaging activity of alginate from Sargassum fusiforme

Food Frontiers, 2023
An alginate (named P1) prepared from Sargassum fusiforme has been proven to have significant anti‐photoaging activity in our previous study. In this study, alginate lyase was used to obtain P1 hydrolysates with different molecular weights, and their ...

SiO2–alginate–melittin nano-conjugates suppress the proliferation of ovarian cancer cells: a controlled release approach leveraging alginate lyase

Cancer Nanotechnology
Background Ovarian cancer treatment is challenged by resistance and off-target effects. Melittin shows promise against cancer but is limited by its instability and harmful cellular interactions. Our study introduces SiO2–alginate–melittin nano-conjugates

Rational Design of Alginate Lyase from Microbulbifer sp. Q7 to Improve Thermal Stability

Marine Drugs, 2019
Alginate lyase degrades alginate by the β-elimination mechanism to produce oligosaccharides with special bioactivities. The low thermal stability of alginate lyase limits its industrial application.

Characterisation of a phylogenetically distinct PL25 family ulvan lyase from a seaweed biomass enriched metagenome

The FEBS Journal, EarlyView.
Ulvan is a polysaccharide available from green seaweed with beneficial properties for various applications. The full potential of ulvan requires enzymatic degradation of the polymer, thus producing ulvan oligosaccharides. This study expands the armoury of characterised ulvan lyases.

3‐Methyl‐1‐Butanol Enhances Postharvest Resistance of Red Grapes to Botrytis cinerea by Activating Phenylpropanoid Metabolism and Antioxidant Defences

Plant Biotechnology Journal, EarlyView.
ABSTRACT Grey mould, caused by Botrytis cinerea, is a significant postharvest disease leading to substantial economic losses in the grape industry. This study investigated the regulatory mechanism of 3‐methyl‐1‐butanol (3M1B), a yeast volatile substance, on B. cinerea resistance in red grapes (Vitis vinifera L.).

Biochemical Characteristics and Variable Alginate-Degrading Modes of a Novel Bifunctional Endolytic Alginate Lyase [PDF]

Applied and Environmental Microbiology, 2017
ABSTRACT Bifunctional alginate lyases can efficiently degrade alginate comprised of mannuronate (M) and guluronate (G), but their substrate-degrading modes have not been thoroughly elucidated to date. In this study, we present Aly1 as a novel bifunctional endolytic alginate lyase of the genus Flammeovirga .
