Ionization of Zwitterionic Amine Substrates Bound to Monomeric Sarcosine Oxidase

Monomeric sarcosine oxidase (MSOX) binds the L-proline zwitterion (pK(a) = 10.6). The reactive substrate anion is generated by ionization of the ES complex (pK(a) = 8.0). Tyr317 was mutated to Phe to determine whether this step might involve proton transfer to an active site base. The mutation does...
