1.5.99.14 | structure of the Kdh holoenzyme, with its three subunits KdhL, KdhM, and KdhS, and their associated cofactors molybdopterin cytosine dinucleotide, two iron-sulfur clusters (Fe2S2), and flavin adenine dinucleotide, respectively. The residues Glu345, Try551, and Glu748 of KdhL participate in substrate binding, and Phe269 and Arg383 of KdhL contribute to stabilize the molybdopterin cytosine dinucleotide conformation |
