mechanism of the reaction is sequential in both directions. Residue Asp183 acts as a catalytic base that deprotonates the C1 hydroxyl group of galactose. The pH-kcat profile of the synthesis of galactose 1-phosphate has a pKa of 6.9 likely due to Asp183. The pH-kcat/KGal profile of the reverse reaction lacks a key pKa required for a direct proton transfer mechanism. Arg36 may lower the pKa of the C1 hydroxyl to facilitate deprotonation |
