Reaction occurs across 3 steps

Step 1
GIF of Reaction Step M0021.stg01

Asp278 deprotonates Lys183, which deprotonates the hydroxyl group of malate, which eliminates a hydride ion that is added to NADP.
0.1 Step 1
GIF of Reaction Step M0116.stg01

Asp132C obtains a proton, causing a rearrangement of the active site.
Step 2
GIF of Reaction Step M0021.stg02

The reduced intermediate decarboxylates with concomitant double bond rearrangement.
0.14 Step 2
GIF of Reaction Step M0116.stg02

NAD eliminates a hydride ion, which adds to NADP.
Step 3
GIF of Reaction Step M0021.stg03

The oxyanion collapses, reducing the C=C with concomitant deprotonation of Tyr112.
0.25 Step 3
GIF of Reaction Step M0116.stg03

Asp132C releases its proton.
Step 4
GIF of Reaction Step M0021.stg04

Tyr112 deprotonates Lys183 which deprotonates Asp278 in an inferred return step.
