description: This entry represents the C-terminal domain found in bacterial 1,4-alpha-glucan branching
  enzymes, such as TTHA1902 from Thermus thermophilus and TK1436 from Thermococcus kodakarensis, which
  belong to the glycoside hydrolase family 57 (GH57). These enzymes catalyse the formation of branch points
  in alpha-glucans by cleavage of an alpha-1,4 glycosidic bond and subsequent transfer of the cleaved-off
  oligosaccharide to a new alpha-1,6 position. This is an alpha-helical domain composed of a four alpha-helical
  bundle. It plays a role in the formation of the active-site cleft, being essential for substrate binding
  and catalysis [[cite:PUB00090452],[cite:PUB00058786]].
