4-Hydroxyproline is found in collagens and collagen-like proteins in animals and in many glycoproteins in plants. Animal prolyl 4-hydroxylases (P4Hs) have been cloned and characterized from many sources, but no plant P4H has been cloned so far. We report here that the genome of Arabidopsis thaliana encodes six P4H-like polypeptides, one of which, a 283-residue soluble monomer, was cloned and characterized here as a recombinant protein. Catalytically critical residues identified in animal P4Hs… CONTINUE READING
