'''ACETYL-COA CARBOXYLASE CARBOXYLTRANSFERASE DOMAIN'''<br />


==Overview==
==Acetyl-CoA Carboxylase Carboxyltransferase Domain==
Acetyl-coenzyme A carboxylases (ACCs) are required for the biosynthesis, and oxidation of long-chain fatty acids. They are targets for therapeutics, against obesity and diabetes, and several herbicides function by, inhibiting their carboxyltransferase (CT) domain. We determined the, crystal structure of the free enzyme and the coenzyme A complex of yeast, CT at 2.7 angstrom resolution and found that it comprises two domains, both belonging to the crotonase/ClpP superfamily. The active site is at, the interface of a dimer. Mutagenesis and kinetic studies reveal the, functional roles of conserved residues here. The herbicides target the, active site of CT, providing a lead for inhibitor development against, human ACCs.

[https://www.uniprot.org/uniprot/ACAC_YEAST ACAC_YEAST] Carries out three functions: biotin carboxyl carrier protein, biotin carboxylase and carboxyltransferase. Involved in the synthesis of very-long-chain fatty acid synthesis which is required to maintain a functional nuclear envelope. Required for acylation and vacuolar membrane association of VAC8 which is necessary to maintain a normal morphology of the vacuole.<ref>PMID:6108218</ref> <ref>PMID:6103540</ref> <ref>PMID:8943372</ref> <ref>PMID:10757783</ref> <ref>PMID:12730220</ref>

== Publication Abstract from PubMed ==
Acetyl-coenzyme A carboxylases (ACCs) are required for the biosynthesis and oxidation of long-chain fatty acids. They are targets for therapeutics against obesity and diabetes, and several herbicides function by inhibiting their carboxyltransferase (CT) domain. We determined the crystal structure of the free enzyme and the coenzyme A complex of yeast CT at 2.7 angstrom resolution and found that it comprises two domains, both belonging to the crotonase/ClpP superfamily. The active site is at the interface of a dimer. Mutagenesis and kinetic studies reveal the functional roles of conserved residues here. The herbicides target the active site of CT, providing a lead for inhibitor development against human ACCs.
