Phycocyanobilin biosynthesis in Galdieria sulphuraria requires isomerization of phycoerythrobilin synthesized by bilin reductases

open access: yesThe FEBS Journal, EarlyView.
The biosynthesis of bilins, tetrapyrroles essential for light harvesting and sensing, is performed by specific enzymes (FDBRs). In Galdieria sulphuraria, both phycobiliprotein types bind phycocyanobilin, despite lacking the canonical synthesizing gene PCYA. Instead, PEBA and PEBB are encoded, producing phycoerythrobilin, proposed to be later isomerized

Reinventing henna: Enzyme‐catalysed colour release from stabilized Lawsonia inermis L. extracts

open access: yesInternational Journal of Cosmetic Science, EarlyView.
The instability and reduced dyeing performance of a cosmetic formulation containing 2‐hydroxy‐1,4‐naphthoquinone (lawsone), derived from Lawsonia inermis L., is demonstrated in comparison to a novel two‐component system. This system comprises one formulation with naturally occurring lawsone precursors and a second containing a specific hydrolase ...

A Comparative Analysis of Maillard‐Derived α‐Dicarbonyl Compounds and Advanced Glycation End Products in Fresh, Wet, Kibble, and Freeze‐Dried Dog Foods

open access: yesJournal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Thermal processing of pet foods can lead to the formation of harmful Maillard reaction products (MRPs), which may compromise nutritional quality and pose health risks to companion animals. This study compared the levels of MRPs in 41 commercial dog foods, including fresh (n = 15), kibble (n = 13), wet (n = 10), freeze‐dried (n = 2), and cold ...
