Reaction occurs across 5 steps

Step 1
GIF of Reaction Step M0050.stg01

The substrate undergoes decarboxylation. The substrate concomitantly deprotonates Lys62 forming UMP.
0.11 Step 1
GIF of Reaction Step M0252.stg01

The nitrogen in the substrate initiates a double bond rearrangement which results in the cyclisation of the intermediate, and deprotonation of Lys110.
Step 2
GIF of Reaction Step M0050.stg02

Lys62 deprotonates water.
0 Step 2
GIF of Reaction Step M0252.stg02

The carboxylic acid group undergoes elimination from the substrate resulting indecarboxylation.
Step 3
No Step with this number present
N/A Step 3
GIF of Reaction Step M0252.stg03

In this inferred step, Lys110 deprotonates water.
Step 4
No Step with this number present
N/A Step 4
GIF of Reaction Step M0252.stg04

Glu159 deprotonates the carbon alpha to the nitrogen in the newly formed ring, initiating the elimination of water and the deprotonation of Lys110.
Step 5
No Step with this number present
N/A Step 5
GIF of Reaction Step M0252.stg05

In this inferred return step, water deprotonates Glu159 and Lys110 deprotonates water.
