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 Mg2+ insertion into protoporphyrin IX (ΔG°′ of circa 25–33 kJ·mol−1). We explored the thermodynamic constraints on magnesium chelatase and demonstrate the effe...
