The enzyme complex is a pseudo-dimeric assembly of a correctly folded and an enzymatically active pro-SI. The sucrase subunit functions as an intramolecular chaperone implicated in the folding of isomaltase subunit. After acquisition of a correct folding in the sucrase subunit this mature form binds tightly to the isomaltase, disrupting its interaction with calnexin. The consequence is that the isomaltase subunit acquires correct folding and sucrase subunit is no longer secreted into the external milieu. |
