Thus, the y-phosphate group of ATP is transferred to some group of the protein and the enzyme phosphoryl intermediate is attacked by the selenide generating the only known direct phosphorus-selenium bond in biology. The ADP, which stays complexed to the enzyme is concomitantly hydrolyzed to AMP, and thus thermodynamically drives the overall reaction. Sulfide does not serve as a substrate even at high concentrations, so SPS is one of the few enzymes that can discriminate between its Se substrate and the sulfur homolog. Recent evidence also indicates that the actual substrate is not free selenide but rather some selenium species generated from selenocysteine via the activity of one of the selenocysteine lyases present in the cell. ...

The 31P 1H -NMR spectrum of compound 26 shows a singlet (S 388 ppm) exhibiting 77Se-satellites, with a coupling constant (2/PSe = 88 Hz) whose magnitude is typical for a two-bond phosphorus-selenium coupling <2003JOM(672)1>.
