Step 1
GIF of Reaction Step M0111.stg01

The N-terminus of Cys1 deprotonates deprotonates water, which deprotonates the thiol group of Cys1, initiating a nucleophilic attack on the amide carbon in an addition reaction.
0.33 Step 1

Glu201 deprotonates the 3-OH of the ribose substrate.
Step 2
GIF of Reaction Step M0111.stg02

The oxyanion initiates an elimination that cleaves ammonia from the bound L-glutamine substrate. Ammonia deprotonates water, which deprotonates the N-terminus of Cys1.
