Binuclear Copper‐Dependent Oxidative Enzymes Involved in Fungal Natural Product Modifications

Journal of the Chinese Chemical Society, Volume 73, Issue 9, Page 1278-1290, September 2026.
This article summarizes recent biochemical characterizations of a new enzyme family named by the authors as binuclear copper‐dependent oxidative enzymes (BiNCOs). Found in fungal natural product biosynthesis, BiNCOs catalyze diverse CH functionalization reactions, including C(sp3)H halogenation, C(sp3)H hydroxylation, C(sp3)O macrocyclization, and ...

Differentiation between Aspergillus flavus and Aspergillus parasiticus from Pure Culture and Aflatoxin-Contaminated Grapes Using PCR-RFLP Analysis of aflR-aflJ Intergenic Spacer. [PDF]

, 2011
Aflatoxins (AFs) represent the most important single mycotoxin-related food safety problem in developed and developing countries as they have adverse effects on human and animal health. They are produced mainly by Aspergillus flavus and A.

Investigation of Aspergillus flavus Infection and Aflatoxin Accumulation in Pulses During Growth and Development

Legume Science, Volume 8, Issue 3, September 2026.
ABSTRACT Aflatoxins (AFL) are mycotoxins produced by Aspergillus flavus that pose major risks to food safety. This study evaluated fungal growth and AFL production in planta across the following five pulse species: chickpeas (Cicer arietinum L.), lentils (Lens culinaris Medik.), peas (Pisum sativum L.), soybeans (Glycine max L.), and with corn (Zea ...

The production of aflatoxin B1 or G1 by Aspergillus parasiticus at various combinations of temperature and water activity is related to the ratio of aflS to aflR expression [PDF]

, 2010
The influence of varying combinations of wateractivity (aw) and temperature on growth, aflatoxin biosynthesisand aflR/aflS expression of Aspergillus parasiticuswas analysed in the ranges 17-42°C and 0.90-0.99 aw.Optimum growth was at 35°C.

Quaternary structures of Streptococcus pneumoniae nucleoside diphosphate kinase: From hexamers to supramolecular assemblies

Protein Science, Volume 35, Issue 9, September 2026.
Abstract The nucleoside diphosphate kinase (NDK) is a key enzyme that controls the balance of nucleotide pools in all living organisms. Beyond this fundamental role, NDKs exert pleiotropic effects in many cellular processes, including cell development, signal transduction, differentiation, tumor metastasis, and gene expression. The quaternary structure

Endobronchial Aspergillosis Presenting as an Isolated Airway Lesion in an Immunocompromised Patient

Respirology Case Reports, Volume 14, Issue 9, September 2026.
Endobronchial Aspergillus infection should be considered in immunocompromised patients presenting with airway obstruction, even in the absence of parenchymal lung involvement. This case highlights the potential for rapid clinical deterioration and the diagnostic challenges in distinguishing endobronchial aspergillosis from more aggressive forms of ...
