HHsearch alignment for GI: 254780873 and conserved domain: cd04892

>cd04892 ACT_AK-like_2 ACT domains C-terminal to the catalytic domain of aspartokinase (AK; 4-L-aspartate-4-phosphotransferase). This CD includes the second of two ACT domains C-terminal to the catalytic domain of aspartokinase (AK; 4-L-aspartate-4-phosphotransferase). The exception in this group, is the inclusion of the first ACT domain of the bifunctional aspartokinase - homoserine dehydrogenase-like enzyme group (ACT_AKi-HSDH-ThrA-like_1) which includes the monofunctional, threonine-sensitive, aspartokinase found in Methanococcus jannaschii and other related archaeal species. AK catalyzes the conversion of aspartate and ATP to aspartylphosphate and ADP. AK is the first enzyme in the pathway of the biosynthesis of the aspartate family of amino acids (lysine, threonine, methionine, and isoleucine) and the bacterial cell wall component, meso-diaminopimelate. One mechanism for the regulation of this pathway is by the production of several isoenzymes of AK with different repressors an
