Step 1
GIF of Reaction Step M0088.stg01

His166 initiates a nucleophilic attack on the alpha-phosphate of the UDP-glucose substrate in a substitution reaction, eliminating glucose phosphate.
1 Step 1
GIF of Reaction Step M0101.stg01

His96 attacks the alpha phosphate of the substrate in a nucleophilic attack which proceeds via a pentavalent transition state and results in the elimination of ADP.
Step 2
GIF of Reaction Step M0088.stg02

Galactose phosphate initiates a nucleophilic attack on the alpha-phosphate of the covalently bound UDP in a substitution reaction, eliminating His166.
0.33 Step 2
GIF of Reaction Step M0101.stg02

ADP deprotonates water, which attacks the phosphate of the covalently bound AMP, eliminating His96 and proceeding via a pentavalent transition state.
