Inhibition of photosynthesis in isolated spinach chloroplasts by Pi is decreased by the presence of PPi and increased with increasing Mg2+ concentration. Previously reported regulation of this photosynthesis by protein factors from spinach leaves appears to be due mostly to pyrophosphate phosphohydrolase (EC 3.6.1.1) activity which converts PPi to Pi and to the effects of PPi and Mg2+ on this pyrophosphatase activity.
无机磷酸盐（Pi）对离体菠菜叶绿体光合作用的抑制作用，在焦磷酸（PPi）存在时会减弱，且随着镁离子（Mg2+）浓度的增加而增强。先前报道的菠菜叶片蛋白因子对这种光合作用的调节作用，似乎主要归因于将PPi转化为Pi的焦磷酸磷酸水解酶（EC 3.6.1.1）活性，以及PPi和Mg2+对该焦磷酸酶活性的影响。
