Protein
Probable phosphopantothenoylcysteine decarboxylase
Organism
Arabidopsis thaliana
Function
Involved in plant growth and salt and osmotic tolerance. Catalyzes the decarboxylation of 4'-phosphopantothenoylcysteine to 4'-phosphopantetheine, a key step in coenzyme A biosynthesis. The enzyme is also able to decarboxylate pantothenoylcysteine to pantothenoylcysteamine.
Similarity
Belongs to the HFCD (homooligomeric flavin containing Cys decarboxylase) superfamily.
