The enzymes threonine deaminase, dihydroxy acid dehydrase and transaminase are controlled by end-product regulation.
2.
The third reaction is the dehydration reaction of ?, ?-dihydroxyisovalerate catalyzed by Dihydroxy acid dehydrase resulting in ?-ketoisovalerate.
3.
This forms 13-hydroperoxylinolenic acid, which is then modified by a dehydrase and undergoes cyclization by allene oxide cyclase to form 12-oxo-phytodienoic acid.
4.
The genes that encode both the Dihydroxy acid dehydrase used in the creation of ?-ketoisovalerate and Transaminase E, as well as other enzymes are encoded on the ilvEDA operon.
5.
Mammalian FAS consists of a homodimer of two identical protein subunits, in which three catalytic domains in the N-terminal section (-ketoacyl synthase ( KS ), malonyl / acetyltransferase ( MAT ), and dehydrase ( DH ) ), are separated by a core region of 600 residues from four C-terminal domains ( enoyl reductase ( ER ),-ketoacyl reductase ( KR ), acyl carrier protein ( ACP ) and thioesterase ( TE ) ).
