Three Semidominant Barley Mutants with Single Amino Acid Substitutions in the Smallest Magnesium Chelatase Subunit Form Defective AAA+Hexamers

Many enzymes of the bacteriochlorophyll and chlorophyll biosynthesis pathways have been conserved throughout evolution, but the molecular mechanisms of the key steps remain unclear. The magnesium chelatase reaction is one of these steps, and it requires the proteins BchI, BchD, and BchH to catalyze...
