Structural and functional insights into extreme thermal stability and activity of two GH12 domains of a multidomain glycosidase from a hyperthermophilic euryarchaeon

The FEBS Journal, EarlyView.
The multidomain glycosidase MDG from the hyperthermophilic euryarchaeon Thermococcus sp. contains five protein domains: three catalytic domains (GH5, GH12‐1, and GH12‐2) and two cellulose‐binding modules (CBM2). In this study, the GH12‐1 and GH12‐2 domains were individually purified and biochemically characterized.

Electrostatic potential as a reactivity scoring function in computer‐assisted enzyme engineering

The FEBS Journal, EarlyView.
We present a computational metric that quantifies the electrostatic complementarity of enzymes to the charge distribution of substrates at the transition state. Implemented in BindScan, this metric accurately predicts functionally relevant mutations in glycoside hydrolases.

Protective effects of Paeonia suffruticosa callus extract in skin through anti‐inflammation and repair UVB‐induced damage

International Journal of Cosmetic Science, EarlyView.
Peony callus extract (PCE) is beneficial for skin anti‐ageing and sensitivity induced by UVB radiation, through decreasing the level of inflammatory factors and matrix metalloproteinases. Furthermore, our research indicates that PCE effectively improves the total collagen content in human skin. Abstract Objective The study investigated effects of peony

Indirubin as a red hair Colourant from Indigofera tinctoria L.

International Journal of Cosmetic Science, EarlyView.
An immediate stable red colour result after application of Indigofera tinctoria L. on hair in the presence of isatin and a reducing agent was achieved. A revised indigo molecule and indirubin synthesis pathway for I. tinctoria L. application including the effect of said additives to the colour outcome is presented.

Evaluation of alveolar bone preservation and oxidative stress reduction with açai in Wistar rats with induced apical periodontitis

International Endodontic Journal, EarlyView.
Abstract Aim This study aimed to investigate the effects of açai on bone and systemic damage caused by apical periodontitis (AP) in an animal model. Methodology In this experimental study, 32 male Wistar rats were randomly allocated into six groups—Control 14 days (n = 4), Control 28 days (n = 4), AP 14 days (n = 4), AP 28 days (n = 4), AP plus açai ...

Assessing the Impact of Vegan Toothpastes on Enamel Color Change and Surface Properties

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To evaluate color (ΔE00) and whiteness index (ΔWID) changes, surface hardness loss (SHL), roughness (Ra), mineral content, and morphology of enamel brushed with vegan toothpastes. Methods Enamel blocks (n = 10/group) were stained with black tea (T0) underwent 15.000 (T1) and 30.000 (T2) toothbrushing cycles with: (n = 10): (AS ...

Salicylic acid: The roles in plant immunity and crosstalk with other hormones

Journal of Integrative Plant Biology, Volume 67, Issue 3, Page 773-785, March 2025.
This review highlights the roles of salicylic acid in plant immunity and summarizes our current understanding of the interactions of salicylic acid with other major plant hormones. ABSTRACT Land plants use diverse hormones to coordinate their growth, development and responses against biotic and abiotic stresses.

A SlMYB78‐regulated bifunctional gene cluster for phenolamide and salicylic acid biosynthesis during tomato domestication, reducing disease resistance

Journal of Integrative Plant Biology, EarlyView.
The tomato transcription factor SlMYB78 controls a key metabolic gene cluster including ENHANCED PSEUDOMONAS SUSCEPTIBILTY 1, encoding a key enzyme that produces disease‐fighting compounds (phenolamides) and immune signals (salicylic acid). During domestication, tomatoes lost a superior variant (SlEPS1HapB), weakening disease resistance; restoring this

The road less taken: Dihydroflavonol 4‐reductase inactivation and delphinidin anthocyanin loss underpins a natural intraspecific flower colour variation

Molecular Ecology, EarlyView.
Abstract Visual cues are of critical importance for the attraction of animal pollinators, however, little is known about the molecular mechanisms underpinning intraspecific floral colour variation. Here, we combined comparative spectral analysis, targeted metabolite profiling, multi‐tissue transcriptomics, differential gene expression, sequence ...
