The ATP-citrate synthase family is responsible for the synthesis of cytosolic acetyl-CoA, a crucial substrate for de novo lipid synthesis, including cholesterol and fatty acids. In animals, these enzymes typically have a homomeric structure, whereas in plants, they are composed of distinct alpha and beta chains. The family plays a central role in lipid metabolism, contributing to the elongation of fatty acids and the biosynthesis of various compounds such as isoprenoids and flavonoids. This family is characterized by its membership in the succinate/malate CoA ligase subunit families, with distinct N-terminal and C-terminal sections. This entry represents the N-terminal ATP-grasp domain.	Domain
