HHsearch alignment for GI: peg_394 and conserved domain: cd04247
>cd04247 AAK_AK-Hom3 AAK_AK-Hom3: Amino Acid Kinase Superfamily (AAK), AK-Hom3; this CD includes the N-terminal catalytic domain of the aspartokinase HOM3, a monofunctional class enzyme found in Saccharomyces cerevisiae and other related AK domains. Aspartokinase, the first enzyme in the aspartate metabolic pathway, catalyzes the conversion of aspartate and ATP to aspartylphosphate and ADP, and in fungi, is responsible for the production of threonine, isoleucine and methionine. S. cerevisiae has a single aspartokinase isoenzyme type, which is regulated by feedback, allosteric inhibition by L-threonine. Recent studies show that the allosteric transition triggered by binding of threonine to AK involves a large change in the conformation of the native hexameric enzyme that is converted to an inactive one of different shape and substantially smaller hydrodynamic size.
