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(More)
Plant and algal prolyl 4-hydroxylases (P4Hs) are key enzymes in the synthesis of cell wall components. These monomeric enzymes belong to the 2-oxoglutarate dependent superfamily of enzymes(More)
Collagen prolyl 4-hydroxylases catalyze the formation of 4-hydroxyproline in -X-Pro-Gly-sequences and have an essential role in collagen synthesis. The vertebrate enzymes are alpha2beta2 tetramers in(More)
