Homotetramer

A homotetramer is a protein complex made up of four identical subunits which are associated but not covalently bound. A heterotetramer is a 4-subunit complex where one or more subunits differ.

Examples of homotetramers include:

  • enzymes like beta-glucuronidase (pictured)
  • export factors such as SecB from Escherichia coli
  • magnesium ion transporters such as CorA.
  • lectins such as Concanavalin A
