the changes in the level of incorporation into the glycoprotein monomers were concomitant with increases in the activity of prolyl hydroxylase ( ec 1.14.11.2 ) incorporation of [ ( 14 ) c ] proline and its subsequent post-translational modification to hydroxyproline in microsomal polypeptides was followed by rapid transfer into the wall with an average t 1/2 of about 7 min .
