We report here four crystal structures of MCD from human, Rhodopseudomonas palustris, Agrobacterium vitis, and Cupriavidus metallidurans at up to 2.3 A resolution. The MCD monomer contains an N-terminal helical domain involved in oligomerization and a C-terminal catalytic domain. The four structures exhibit substantial differences in the organization of the helical domains and, consequently, the oligomeric states and intersubunit interfaces. Unexpectedly, the MCD catalytic domain is structurally homologous to those of the GCN5-related N-acetyltransferase superfamily, especially the curacin A polyketide synthase catalytic module, with a conserved His-Ser/Thr dyad important for catalysis. Our structures, along with mutagenesis and kinetic studies, provide a molecular basis for understanding pathogenic mutations and catalysis, as well as a template for structure-based drug design. Crystal structures of malonyl-coenzyme a decarboxylase provide insights into its catalytic mechanism and disease-causing mutations.,Froese DS, Forouhar F, Tran TH, Vollmar M, Kim YS, Lew S, Neely H, Seetharaman J, Shen Y, Xiao R, Acton TB, Everett JK, Cannone G, Puranik S, Savitsky P, Krojer T, Pilka ES, Kiyani W, Lee WH, Marsden BD, von Delft F, Allerston CK, Spagnolo L, Gileadi O, Montelione GT, Oppermann U, Yue WW, Tong L Structure. 2013 Jul 2;21(7):1182-92. doi: 10.1016/j.str.2013.05.001.
