Old player, new roles: defining the role of the plastidial phosphorylase

New Phytologist, Volume 247, Issue 4, Page 1622-1632, August 2025.
Summary The plastidial phosphorylase (Pho1 or Phs1; E.C. 2.4.1.1) is a ubiquitous enzyme among plants that catalyzes the formation and degradation of glucans. Although the first report connecting Pho1 with starch metabolism came out > 80 years ago, its precise role is still a matter of debate.

HR‐MS Analysis of the Covalent Binding of Edaravone to 5‐Formylpyrimidine Bases and a DNA Oligonucleotide Containing a 5‐Formylcytidine Residue

Rapid Communications in Mass Spectrometry, Volume 39, Issue 14, 30 July 2025.
ABSTRACT Rationale Edaravone (EDA) is a radical scavenger and an antioxidant drug approved to treat amyotrophic lateral sclerosis and used as a research tool to explore treatment of neurodegenerative diseases and cancers. It is also a reactive agent, known as PMP (1‐phenyl‐3‐methyl‐5‐pyrazolone), used for the analysis of polysaccharides composition ...

Biosynthesis of Ephedrine Initiated by Pyridoxal Phosphate‐Dependent Formation of Cathinone

ChemBioChem, Volume 26, Issue 14, July 18, 2025.
An alternative pathway to ephedra alkaloids via (S)–cathinone is investigated in plants. This pathway circumvents the formation of 1‐phenylpropane‐1,2‐dione as an intermediate, which has been part of the predominantly postulated biosynthetic pathway for the last decades. This alternative pathway involves an enzymatic pyridoxal phosphate (PLP)‐dependent

Is the Generation of Active Vitamin B6 Dependent upon Riboflavin Status? New Analysis of Data from RCTs of Riboflavin Supplementation

Proceedings
Background and objectives: Riboflavin in the form flavin mononucleotide (FMN) acts as a cofactor for the pyridoxine phosphate oxidase required to generate pyridoxal 5′-phosphate (PLP), the active form of vitamin B6 in tissues.
