AMPK is a heterotrimer: <br /> <scene name='49/493732/Cv/10'>AMPK α subunit</scene> is the catalytic subunit and contains <scene name='49/493732/Cv/11'>Thr174 (TPO) which undergoes phosphorylation</scene>. <br /> <scene name='49/493732/Cv/5'>AMPK β subunit</scene> is a scaffold on which the heterotrimer assembles. There are 2 β subunits. β subunit contains <scene name='49/493732/Cv/12'>phosphorylated Ser108 (SEP)</scene>. <br /> <scene name='49/493732/Cv/8'>AMPK γ subunit</scene> detects shifts in AMP:ATP ratio via its 4 cystathionine β synthase (CBS) domains. <scene name='49/493732/Cv/13'>The active site binds 3 AMPs</scene>.<ref>PMID:25412657</ref> | AMPK is a heterotrimer: <br /> <scene name='49/493732/Cv/10'>AMPK α subunit</scene> is the catalytic subunit and contains <scene name='49/493732/Cv/11'>Thr174 (TPO) which undergoes phosphorylation</scene>. <br /> <scene name='49/493732/Cv/5'>AMPK β subunit</scene> is a scaffold on which the heterotrimer assembles.
