5'-methylthioadenosine + phosphate | the [3'-2H] kinetic isotope effect is consistent with a unique H3'-endo-exo configuration and 3'-hydroxyl polarization without full ionization at the MTAN transition state. The MTAN transition state is a fully dissociative (SN1), ribooxacarbenium-like structure with its C1'-N9 distance larger than 3.2 A. The ribosyl moiety adopts a H3'-endo-exo transition conformation, and the 3'-OH residue is partially polarized by the adjacent carboxylate with a hydrogen bond distance of 2.83 A. The MTAN transition state has a geometry between the unrestrained H3'-endo 5'-methylthioadenosine substrate and a fully developed 3'-exo ribooxacarbenium ion | Streptococcus pneumoniae | adenine + 5-methylthio-D-ribose 1-phosphate | - |
