New Family of Ulvan Lyases Identified in Three Isolates from the Alteromonadales Order*

open access: yesJournal of Biological Chemistry, 2016
Ulvan is the main polysaccharide component of the Ulvales (green seaweed) cell wall. It is composed of disaccharide building blocks comprising 3-sulfated rhamnose linked to d-glucuronic acid (GlcUA), l-iduronic acid (IdoUA), or d-xylose (Xyl).

Cross‐Cohort Gut Microbiome Signatures of Irritable Bowel Syndrome Presentation and Treatment

open access: yesAdvanced Science, Volume 11, Issue 41, November 6, 2024.
Irritable Bowel Syndrome (IBS) is a prevalent disorder of gut‐brain interaction, affecting ≈11% of the global population. This meta‐analysis identified consistent gut microbiome signatures associated with IBS across studies in distinct geographies and cataloged microbiota‐targeted diet patterns for microbiome modulation in IBS.

Chemical Modification and Kinetic Studies on Glucarate Hydro‐Lyase from a Species of Pseudomonas A [PDF]

open access: yesEuropean Journal of Biochemistry, 1972
Glucarate hydro‐lyase, obtained from cells of Pseudomonas A grown on glucarate as the sole source of carbon, was purified 40‐fold in 70% yield. The effects of a variety of chemical modifiers and competitive inhibitors on the enzyme activity were studied.

Enantioselective synthesis of cyanohydrins catalysed by hydroxynitrile lyases - a review.

open access: yesOrganic and biomolecular chemistry, 2016
The first enantioselective synthesis was the selective addition of cyanide to benzaldehyde catalysed by a hydroxynitrile lyase (HNL). Since then these enzymes have been developed into a reliable tool in organic synthesis.

Novel Palladium Hydride Surface Enabling Simultaneous Bacterial Killing and Osteogenic Formation through Proton Capturing and Activation of Antioxidant System in Immune Microenvironments

open access: yesAdvanced Materials, Volume 36, Issue 31, August 1, 2024.
A palladium hydride (PdHx) film, fabricated on titanium implants, exhibits a lattice capable of capturing protons within the bacterial microenvironment, consequently inducing bacterial death. Furthermore, it mimics human antioxidant systems, reshaping the osteogenic immune microenvironment and promoting osteogenesis.

De‐nitrosylation Coordinates Appressorium Function for Infection of the Rice Blast Fungus

open access: yesAdvanced Science, Volume 11, Issue 26, July 10, 2024.
Nitric oxide (NO) is essential for Magnaporthe oryzae development and stress response. This research reveals that GSNOR‐mediated de‐nitrosylation is vital for appressorium formation and crucial for fungal infection. Proteomic analysis identifies a broad S‐nitrosylation network, with GSNOR regulating key proteins for infection.

Extra-Mitochondrial CU/Zn Superoxide Dismutase (SOD1) Is Dispensable for Protection Against Oxidative Stress but Mediates Peroxide Signaling in Saccharomyces Cerevisiae [PDF]

open access: yes, 2019
Cu/Zn Superoxide Dismutase (Sod1) is a highly conserved and abundant metalloenzyme that catalyzes thedisproportionation of superoxide radicals into hydrogen peroxide and molecular oxygen.

Mitochondrial Oxidative Stress and Calcium-Dependent Permeability Transition are Key Players in the Mechanisms of Statins-Associated Side Effects [PDF]

open access: yes, 2017
Statins are cholesterol-lowering medicines utilized worldwide and are associated with reduced risk of cardiovascular mortality and events. However, 0.5–10% of patients suffer from adverse effects especially on skeletal muscle.

Litchi postharvest physiology and handling

open access: yesCrop Science, Volume 64, Issue 4, Page 2014-2063, July/August 2024.
Abstract Litchi (Litchi chinensis Sonn.) fruit, with its bright red color and sweet and juicy aril, is an important fruit crop in Asia, Africa, Australia, and South America. A major cause of the postharvest loss of litchi fruit is browning and decay.
