Discovery of a novel iota carrageenan sulfatase isolated from the marine bacterium Pseudoalteromonas carrageenovora

Frontiers in Chemistry, 2014
Carrageenans are sulfated polysaccharides extracted from the cell wall of some marine red algae. These polysaccharides are widely used as gelling, stabilizing, and viscosifying agents in the food and pharmaceutical industries.

NTAQ1 Promotes Hepatocellular Carcinoma Growth by Facilitating the Protein Degradation of the Tumor Suppressor PRDM2

Cancer Science, EarlyView.
Copy number variation analysis in The Cancer Genome Atlas identified NTAQ1 as a potential driver of HCC progression. NTAQ1 accelerates tumor growth by promoting the degradation of the tumor suppressor protein PRDM2, thereby impairing DNA repair and suppressing apoptosis. These findings indicate that NTAQ1 could be a valuable target for the treatment of

Hormone crosstalk in wound stress response: wound-inducible amidohydrolases can simultaneously regulate jasmonate and auxin homeostasis in Arabidopsis thaliana

, 2016
Jasmonate (JA) and auxin are essential hormones in plant development and stress responses. While the two govern distinct physiological processes, their signaling pathways interact at various levels.

Methyl Jasmonate Seed Priming Mitigates the Defence‐Growth Trade‐Off and Tailors Plant Response to Specific Pests

Plant, Cell &Environment, EarlyView.
ABSTRACT Seed defence priming is emerging as a novel, cost‐efficient and environmentally safe tool for pest management. It has been proposed as a means to uncouple the defence‐growth trade‐off in plants by enhancing defence responses with minimal fitness costs, but the mechanisms underlying this role remain elusive.

The Acylamide Amidohydrolase of Candida utilis: Purification and Properties [PDF]

Journal of General Microbiology, 1969
SUMMARY: The amidohydrolase formed in the later stages of growth on glucose peptone medium by Candida utilis was purified 60-fold from cell-free extracts. The purified enzyme hydrolysed mono- and di-carboxylic acid amides, benzamide, nicotinamide, pyrazinamide and certain β-hydroxyl substituted fatty acid amides, was inactive on l-asparagine and l ...

The BAHD Acyltransferase Gene Family: Evolutionary Dynamics, Biochemical Mechanisms, and Roles in Plant Stress Adaptation

Plant Biotechnology Journal, Volume 24, Issue 6, Page 4139-4158, June 2026.
BAHD acyltransferases drive metabolic diversification in plants by coupling conserved catalytic scaffolds with regulatory flexibility, enabling stress adaptation and ecological specialisation. ABSTRACT BAHD acyltransferases constitute one of the most versatile enzyme superfamilies in plants, catalysing the acylation of alcohols, amines, polyamines, and

Endogenous Ceramide 24:1 Constrains Th17‐Driven Neutrophilic Inflammation by Antagonizing EP2 Signaling

Advanced Science, Volume 13, Issue 29, 22 May 2026.
Cer24:1 levels are reduced in neutrophilic asthma and inversely correlate with disease severity and airway neutrophilia. Restoring Cer24:1 suppresses pathogenic Th17 differentiation by engaging EP2 on CD4+ T cells, thereby dampening the JAK2–STAT3–RORγt axis and reducing IL‐17 production.
