Class I glutaredoxins (GRXs) are catalytically active oxidoreductases and considered key proteins mediating reversible glutathionylation and deglutathionylation of protein thiols during development and stress responses. To narrow in on putative target proteins, it is mandatory to know the subcellular localization of the respective GRXs and to understand their catalytic activities and putative redundancy...
During chlorophyll degradation, large amounts of the isoprenoid alcohol phytol are released. The pathway of phytol catabolism has been studied in humans, because chlorophyll is part of the human diet, but little is known for plants. In humans, phytanoyl‐CoA derived from phytol is degraded via α‐oxidation by phytanoyl‐CoA hydroxylase (PAHX) and 2‐hydroxy‐phytanoyl‐CoA lyase (HPCL). Arabidopsis contains...
