Reaction occurs across 7 steps

0.1232

Reaction occurs across 2 steps

Step 1
GIF of Reaction Step M0201.stg01

Reaction occurs in the alpha-subunit. The bicarbonate is deprotonated by an unidentified base. The activate bicarbonate then acts as a nucleophile and attacks the gamma-phosphate in a substitution reaction, liberating ADP. Mg(II) stabilises/activates the ATP
0.28 Step 1
GIF of Reaction Step M0070.stg01

The substrate undergoes decarboxylation, with concomitant double bond rearrangement. The newly formed oxyanion is stabilised by the backbone amides of His66 and Gly110
Step 2
GIF of Reaction Step M0201.stg02

Reaction occurs in the alpha-subunit. The phosphorylated bicarbonate undergoes a decarboxylation reaction (E1cb) to liberate carbon dioxide and phosphate.
0.2 Step 2
GIF of Reaction Step M0070.stg02

The oxyanion collapses, initiating double bond rearrangement. The substrate deprotonates an unidentified base to form the final product.
Step 3
GIF of Reaction Step M0201.stg03

Reaction occurs in the alpha-subunit. The phosphate deprotonates one of the N-H groups of biotin with concomitant tautomerisation to produce an oxyanion.
N/A Step 3
No Step with this number present
Step 4
GIF of Reaction Step M0201.stg04

Reaction occurs in the alpha-subunit. The oxyanion re-forms the carbonyl group, causing the C=N bond of the activated biotin to add to the carbon dioxide in a nucleophilic manner.
N/A Step 4
No Step with this number present
Step 5
GIF of Reaction Step M0201.stg05

Reaction occurs in the beta-subunit. Once the carboxylated biotin has relocated to the beta-subunit, the biotin undergoes a decarboxylation reaction (E1cb) to liberate carbon dioxide and the activated biotin molecule. the main chain amides of Gly419B and Ala420B stabilise the oxyanion of the activated biotin.
N/A Step 5
No Step with this number present
Step 6
GIF of Reaction Step M0201.stg06

Reaction occurs in the beta-subunit. The oxyanion re-forms the carbonyl group, causing the C=N bond of the activated biotin to deprotonate the propanoyl-CoA with concomitant tautomerisation. The main chain amides of Gly182 and Gly183 stabilise the activated propanoyl-CoA, the main chain amides of Gly419B and Ala420B stabilise the oxyanion of the activated biotin.
N/A Step 6
No Step with this number present
Step 7
GIF of Reaction Step M0201.stg07

Reaction occurs in the beta-subunit. The oxyanion re-forms the carbonyl group causing the C=C bond of the activated propanoyl-CoA to add to the carbon dioxide molecule in an electrophilic manner.
N/A Step 7
No Step with this number present
