Enzymes

General function:
Involved in hydroxymethyl-, formyl- and related transferase activity
Specific function:
Bifunctional enzyme that catalyzes the oxidative decarboxylation of UDP-glucuronic acid (UDP-GlcUA) to UDP-4-keto- arabinose (UDP-Ara4O) and the addition of a formyl group to UDP-4- amino-4-deoxy-L-arabinose (UDP-L-Ara4N) to form UDP-L-4-formamido- arabinose (UDP-L-Ara4FN). The modified arabinose is attached to lipid A and is required for resistance to polymyxin and cationic antimicrobial peptides
Gene Name:
arnA
Uniprot ID:
P77398
Molecular weight:
74288
Reactions
UDP-alpha-D-glucuronate + NAD(+) = UDP-beta-L-threo-pentapyranos-4-ulose + CO(2) + NADH.
10-formyltetrahydrofolate + UDP-4-amino-4-deoxy-beta-L-arabinose = 5,6,7,8-tetrahydrofolate + UDP-4-deoxy-4-formamido-beta-L-arabinose.
General function:
Involved in transaminase activity
Specific function:
Catalyzes the conversion of UDP-4-keto-arabinose (UDP- Ara4O) to UDP-4-amino-4-deoxy-L-arabinose (UDP-L-Ara4N). The modified arabinose is attached to lipid A and is required for resistance to polymyxin and cationic antimicrobial peptides
Gene Name:
arnB
Uniprot ID:
P77690
Molecular weight:

Reactions
UDP-4-amino-4-deoxy-beta-L-arabinose + 2-oxoglutarate = UDP-beta-L-threo-pentapyranos-4-ulose + glutamate.
