We apologize for Proteopedia being slow to respond. For the past two years, a new implementation of Proteopedia has been being built. Soon, it will replace this 18-year old system. All existing content will be moved to the new system at a date that will be announced here.

Up to now there is no catalytic activity known for this domain. Quite the contrary regarding the <scene name='68/686749/C-terminal_domain/1'>C-terminal domain</scene> of the isoprene synthase: This domain shows up an 𝛼-helical class I terpenoid synthase fold and contains the active site which is surrounded by five 𝛼-helices. The active site of the enzyme is located in a deep hydrophobic pocket which ensures a protection of the reaction intermediate from water.<ref name="Koch"/> | Up to now there is no catalytic activity known for this domain.
