Catalytic turnover triggers exchange of subunits of the magnesium chelatase AAA+ motor unit.

The Journal of biological chemistry - 16 Aug 2013

Abstract excerpt

The ATP-dependent insertion of Mg(2+) into protoporphyrin IX is the first committed step in the chlorophyll biosynthetic pathway. The reaction is catalyzed by magnesium chelatase, which consists of three gene products: BchI, BchD, and BchH. The BchI and BchD subunits belong to the family of AAA+ proteins (ATPases associated with various cellular activities) and form a two-ring complex with six BchI subunits in...
