In vitro hydroxylation of proline in the collagen of the cysticercus of Taenia solium.
1. In vitro hydroxylation of proline in cysticercus collagen was carried out using two different vertebrate enzymes. 2. Chick embryo enzyme is more active on cysticercus collagen than new-born rabbit enzyme. 3. Hydroxylation of cysticercus collagen is more efficient at 40 than at 37 degrees C. 4. No prolyl hydroxylase activity was detected in cysticercus extracts. 5. Collagen from the adult tapeworms Taenia solium and T. saginata lack hydroxyproline. 6. SLS crystallites from T. solium and T. saginata collagen show the same band pattern as cysticercus collagen.
