Cocrystal structures of the mammalian AMPK core reveal occlusion of nucleotide-binding site 3 of the gamma subunit in the presence of ATP. However, site 3 is occupied in the presence of AMP. Mutagenesis studies indicate that sites 3 and 4 are important for AMPK allosteric activation. AMP-activated protein kinase undergoes nucleotide-dependent conformational changes.,Chen L, Wang J, Zhang YY, Yan SF, Neumann D, Schlattner U, Wang ZX, Wu JW Nat Struct Mol Biol. 2012 Jun 3;19(7):716-8. doi: 10.1038/nsmb.2319.
