MPI must convert an aldose (mannose) to a ketose (fructose), in addition to opening and closing the rings for these sugars. In humans a mechanism has been suggested which involves a hydrogen transfer between C1 and C2, mediated by Tyr278, and the movement of a proton from O1 and O2 mediated by the associated Zn ion. The ring opening step may be catalyzed by His99 an… WebWe would like to show you a description here but the site won’t allow us.
