ATPase activity of magnesium chelatase subunit I is required to maintain subunit D in vivo.

European journal of biochemistry - 1 Jun 2004

Lake Vanessa, Olsson Ulf, Willows Robert D, Hansson Mats

Abstract excerpt

During biosynthesis of chlorophyll, Mg(2+) is inserted into protoporphyrin IX by magnesium chelatase. This enzyme consists of three different subunits of approximately 40, 70 and 140 kDa. Seven barley mutants deficient in the 40 kDa magnesium chelatase subunit were analysed and it was found that this subunit is essential for the maintenance of the 70 kDa subunit, but not the 140 kDa subunit. The 40 kDa subunit...
