PFK is a <scene name='Zach_Westrick_Sandbox/Tetramer/1'>Homotetramer</scene> that acts as a dimer of dimers, similar to hemoglobin.<ref>PMID:6115424</ref>. One half of each dimer is involved in the binding of ATP, while the other is involved with substrate binding and also contains an allosteric site. <ref>PMID:2975709</ref>. One subunit with ATP and F6P bound can be seen below. | |||
PFK's <scene name='Zach_Westrick_Sandbox/Secondary_structure/3'>Secondary Structure</scene> puts it in an alpha and beta class. Each unit is comprised of two domains that sandwich parallel beta sheets in between alpha helices. The outer most beta sheets of the larger domain, however, are anti-parallel. This is best seen in the <scene name='Zach_Westrick_Sandbox/One_subunit/1'>4pfk image</scene>. | |||
