Subunits

EC Number Subunits Comment Organism
4.6.1.19 dimer the dimer configuration of full-length enzyme arises from the intertwining of two promoters through a 155° twisting action across the ANK domain-PK domain junction, which gives rise to the appearance of an exchange of ANK and PK domains between protomers, back-to-back dimer arrangement. Dimerization of the ANK domain is facilitated by a head-to-tail arrangement with concave surfaces facing inward. Kinase domain-ANK domain contacts, overview Homo sapiens
