The catalytic power of magnesium chelatase: a benchmark for the AAA (+) ATPases

In the first committed reaction of chlorophyll biosynthesis, magnesium chelatase couples ATP hydrolysis to the thermodynamically unfavorable Mg(2+) insertion into protoporphyrin IX (ΔG°′ of circa 25–33 kJ·mol(−1)). We explored the thermodynamic constraints on magnesium chelatase and demonstrate the...
