This entry represents the ACT domain, which is found twice in Aspartate kinase from Methanocaldococcus jannaschii, the enzyme that catalyses the phosphorylation of aspartic acid [6]. This domain folds as a four-stranded antiparallel sheet with two alpha-helices parallel to the sheet and located on one side of the sheet [1].	Domain

This family of domains generally have a regulatory role. ACT domains are linked to a wide range of metabolic enzymes that are regulated by amino acid concentration. Pairs of ACT domains bind specifically to a particular amino acid leading to regulation of the linked enzyme. The ACT domain is found in: D-3-phosphoglycerate dehydrogenase EC:1.1.1.95 Swiss:P08328, which is inhibited by serine [1]. Aspartokinase EC:2.7.2.4 Swiss:P53553, which is regulated by lysine. Acetolactate synthase small regulatory subunit Swiss:P00894, which is inhibited by valine. Phenylalanine-4-hydroxylase EC:1.14.16.1 Swiss:P00439, which is regulated by phenylalanine. Prephenate dehydrogenase EC:4.2.1.51 Swiss:P21203. formyltetrahydrofolate deformylase EC:3.5.1.10, Swiss:P37051, which is activated by methionine and inhibited by glycine. GTP pyrophosphokinase EC:2.7.6.5 Swiss:P11585	Domain
