21. Ornithine decarboxylase can catalyse the decarboxylation of DFMO instead of ornithine , as shown above. 22. Ornithine carbamoyltransferase ( OTCase ) catalyses the conversion of ornithine and carbamoyl phosphate to citrulline.23. Ornithine carbamoyltransferase ( OTCase ) catalyses the conversion of ornithine and carbamoyl phosphate to citrulline. 24. Polyamine metabolism is regulated by the activity of the enzyme ornithine decarboxylase ( ODC ). 25. Using his Warburg manometer, he mixed a slice of liver with purified ornithine and citrulline. 26. Ornithine translocase deficiency belongs to a class of metabolic disorders referred to as urea cycle disorders.27. The systematic name of this enzyme class is "'ornithine racemase " '. 28. Group III comprises prokaryotic ornithine and lysine decarboxylase and the prokaryotic biodegradative type of arginine decarboxylase. 29. The biosynthesis begins with L-Glutamine, which is derived to L-ornithine in plants. 30. The biosynthesis of scopolamine begins with the decarboxylation of L-ornithine to putrescine by ornithine decarboxylase.
