'''Structure of a Threonine Sensitive Aspartokinase from Methanococcus jannaschii Complexed with Mg-ADP and Aspartate'''
===Structure of a Threonine Sensitive Aspartokinase from Methanococcus jannaschii Complexed with Mg-ADP and Aspartate===




==Overview==
<!--  
The activation of the beta-carboxyl group of aspartate catalyzed by aspartokinase is the commitment step to amino-acid biosynthesis in the aspartate pathway. The first structure of a microbial aspartokinase, that from Methanococcus jannaschii, has been determined in the presence of the amino-acid substrate L-aspartic acid and the nucleotide product MgADP. The enzyme assembles into a dimer of dimers, with the interfaces mediated by both the N- and C-terminal domains. The active-site functional groups responsible for substrate binding and specificity have been identified and roles have been proposed for putative catalytic functional groups.
