Enzymatic Basis for the Oxidative Branch of Aromatic Amino Acid Fermentation Leading to p‐cresol Formation

Advanced Science, Volume 13, Issue 34, 19 June 2026.
In anaerobic bacteria, tyrosine serves as an electron donor in the oxidative Stickland fermentation branch, generating p‐hydroxyphenylacetate, ATP and reduced ferredoxin for decarboxylation into p‐cresol. ABSTRACT The phenolic metabolite p‐cresol is a byproduct of tyrosine fermentation by certain strictly anaerobic bacteria, including the human gut ...

Transcriptomic analysis reveals the hepatic response mechanisms of the Chinese spiny frog (Quasipaa spinosa) to Citrobacter freundii infection

Journal of the World Aquaculture Society, Volume 57, Issue 3, June 2026.
Abstract To elucidate the pathogen and host response mechanisms underlying mass mortality in Quasipaa spinosa, dominant bacteria were isolated from diseased individuals and identified as Citrobacter freundii by morphological, physiological, and biochemical characterization, 16S rRNA sequencing, and phylogenetic analysis.

Hypoxic and Fe‐Responses are Regulated by the ERFVII Factors and the PCO Branch of the N‐Degron Pathway According to Iron Availability

Plant, Cell &Environment, Volume 49, Issue 6, Page 3363-3380, June 2026.
ABSTRACT In plants, iron homeostasis and oxygen metabolism are strictly related, indeed several Fe‐requiring enzymes catalyze reactions that also involve O2 as a reagent, product, entry or end point of the pathway. Oxygen sensing itself relies on the Fe‐dependent enzymes Plant cysteine oxidases.
