Metabolite Identification
Common NameUDP-4-Deoxy-4-formamido-beta-L-arabinose
DescriptionUDP-4-Deoxy-4-formamido-beta-L-arabinose is an intermediate in the polymixin resistance pathway. It is a substrate for the enzyme Bifunctional polymyxin resistance protein ArnA 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. Some Gram-negative bacteria, specifically Salmonella typhimurium and Escherichia coli, can become resistant to polymyxin by the modification of their lipid A structure via the attachment of 4-amino-4-deoxy-L-arabinopyranose (L-Ara4N) groups to one or more phosphate groups. This addition causes an absolute increase in lipid A charge, thus lowering the affinity of positively charged polymyxins.
