abstract
Oxygen-18 was used to study the synthesis of collagen hydroxyproline in vivo by chick embryos. The oxygen incorporated into the hydroxyl group was found to originate from atmospheric oxygen rather than water, and therefore the results indicate that an oxygenase mechanism is involved in the conversion of proline to hydroxyproline. Since earlier studies have shown that free proline is not hydroxylated directly, it appears that the oxygen acceptor in this case is an activated form of proline. 1963.
