Reaction occurs across 4 steps

Step 1
GIF of Reaction Step M0050.stg01

The substrate undergoes decarboxylation. The substrate concomitantly deprotonates Lys62 forming UMP.
0 Step 1
GIF of Reaction Step M0114.stg01

The nitrogen of trimethylamine initiates the elimination of a hydride ion, which is added to FMN.
Step 2
GIF of Reaction Step M0050.stg02

Lys62 deprotonates water.
0 Step 2
GIF of Reaction Step M0114.stg02

The first single electron transfer from FMN to ETF, which passes through a single iron-sulfur cluster.
Step 3
No Step with this number present
N/A Step 3
GIF of Reaction Step M0114.stg03

The second single electron transfer from FMN to ETF, which passes through a single iron-sulfur cluster. The transfer is facilitated by the abstraction of a proton from the FMN by water.
Step 4
No Step with this number present
N/A Step 4
GIF of Reaction Step M0114.stg04

The product of the enzyme undergoes spontaneous hydrolysis outside of the active site to produce formaldehyde and dimethylamine.
