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
