We confronted the kinetic parameters of the sulfoconjugation of synthetic ( 1R ) - normetanephrine and ( 1S ) - normetanephrine by recombinant human SULT1A3 to a docking model of each normetanephrine enantiomer with SULT1A3 and the 3 ' - phosphoadenosine - 5 ' - phosphosulfate cofactor on the basis of molecular modeling and molecular dynamics simulations of the stability of the complexes .
 ( 1R ) - normetanephrine, ( 1S ) - normetanephrine, normetanephrine, 3 ' - phosphoadenosine - 5 ' - phosphosulfate
