Hydroxymethylbilane Synthase
|
D011163 |
[An enzyme that catalyzes the tetrapolymerization of the monopyrrole PORPHOBILINOGEN into the hydroxymethylbilane preuroporphyrinogen (UROPORPHYRINOGENS) in several discrete steps. It is the third enzyme in the 8-enzyme biosynthetic pathway of HEME. In humans, deficiency in this enzyme encoded by HMBS (or PBGD) gene results in a form of neurological porphyria (PORPHYRIA, ACUTE INTERMITTENT). This enzyme was formerly listed as EC 4.3.1.8

Hydroxymethylglutaryl-CoA Reductases, NAD-Dependent
|
D025781 |
[Specific hydroxymethylglutaryl CoA reductases that utilize the cofactor NAD. This class of enzymes performs a catabolic role in microorganisms such as Pseudomonas mevalonii where it oxidatively acetylates MEVALONIC ACID to form 3-HYDROXY-3-METHYLGLUTARYL-COENZYME A and NADH.

|
Hydroxymethylglutaryl-CoA Synthase
|
D006904 |
[An enzyme that catalyzes the synthesis of hydroxymethylglutaryl-CoA from acetyl-CoA and acetoacetyl-CoA. This is a key enzyme in steroid biosynthesis. This enzyme was formerly listed as EC 4.1.3.5.
