The biosynthesis of scopolamine begins with the decarboxylation of L-ornithine to putrescine by ornithine decarboxylase.
32.
Thus the ornithine cycle was established, and it was the first metabolic cycle to be discovered.
33.
Subsequent steps are catalyzed by the enzymes ornithine acetyltransferase ( OAT ), and this yields ornithine.
34.
Subsequent steps are catalyzed by the enzymes ornithine acetyltransferase ( OAT ), and this yields ornithine.
35.
P5CS catalyzes the phosphorylation-and intermediate in the interconversions of proline, ornithine, and glutamate.
36.
The biosynthesis begins with L-Glutamine, which is derived from L-ornithine in plants.
37.
Lysine 69 on ornithine decarboxylase ( ODC ) binds the cofactor pyridoxal phosphate to form a Schiff base.
38.
The " SLC25A15 " gene provides instructions for making a protein called a mitochondrial ornithine transporter.
39.
L-ornithine is converted to L-arginine, which is then decarboxylated via PLP to form agmatine.
40.
Group IV comprises eukaryotic ornithine and lysine decarboxylase and the prokaryotic biosynthetic type of arginine decarboxylase and diaminopimelate decarboxylase.
