Cosa (chi) è (2,2,3-trimethyl-5-oxocyclopent-3-enyl)acetyl-CoA synthase - definizione
Hydroxymethylglutaryl-CoA synthase
CLASS OF ENZYMES
HMG-CoA synthase; EC 2.3.3.10; 3-hydroxy-3-methylglutaryl-coa synthase 1; Acetyl-CoA:acetoacetyl-CoA C-acetyltransferase (thioester-hydrolysing, carboxymethyl-forming); Hydroxymethylglutaryl-coa synthase
In molecular biology, hydroxymethylglutaryl-CoA synthase or HMG-CoA synthase is an enzyme which catalyzes the reaction in which acetyl-CoA condenses with acetoacetyl-CoA to form 3-hydroxy-3-methylglutaryl-CoA (HMG-CoA). This reaction comprises the second step in the mevalonate-dependent isoprenoid biosynthesis pathway.
Acetyl-CoA carboxylase
A PROTEIN COMPLEX THAT CATALYZES THE FIRST STEP IN LONG-CHAIN FATTY ACID BIOSYNTHESIS. FOR EXAMPLE, IN E. COLI THE COMPLEX IS HETEROHEXAMERIC AND COMPOSED OF BIOTIN CARBONYL CARRIER PROTEIN, BIOTIN CARBOXYLASE AND THE ACETATE COA-TRANSFERASE COMPLEX.
Acetyl-coa carboxylase; ACCase; Acetyl coa carboxylase; Acetyl CoA carboxylase; EC 6.4.1.2; Acetyl-CoA:carbon-dioxide ligase (ADP-forming); Acetyl coenzyme A carboxylase; TaACC
Acetyl-CoA carboxylase (ACC) is a biotin-dependent enzyme () that catalyzes the irreversible carboxylation of acetyl-CoA to produce malonyl-CoA through its two catalytic activities, biotin carboxylase (BC) and carboxyltransferase (CT). ACC is a multi-subunit enzyme in most prokaryotes and in the chloroplasts of most plants and algae, whereas it is a large, multi-domain enzyme in the cytoplasm of most eukaryotes.
3-Hydroxy-3-methylglutaryl-CoA lyase
CLASS OF ENZYMES
Hydroxymethylglutaryl-CoA lyase; HMG-CoA lyase; EC 4.1.3.4; (S)-3-hydroxy-3-methylglutaryl-CoA acetoacetate-lyase (acetyl-CoA-forming); HMGCL; 3-hydroxy-3-methylglutaryl-CoA lyase
3-Hydroxy-3-methylglutaryl-CoA lyase (or HMG-CoA lyase) is an enzyme ( that in human is encoded by the HMGCL gene located on chromosome 1. It is a key enzyme in ketogenesis (ketone body formation).
