2.7.9.3 | ATP + selenide + H2O = AMP + selenophosphate + phosphate |
SPS catalyzes the exchange of the ATP gamma-phosphate group in the absence of selenide, suggesting that the beta-gamma-phosphate bond, but not the alpha-beta-phosphate bond, could be the initial cleavage site, formation of a phosphorylated enzyme intermediate, catalytic mechanism, overview |

2.7.9.3 | ATP + selenide + H2O = AMP + selenophosphate + phosphate |
the existence of a pyrophosphorylated enzyme intermediate can be excluded |
