10-formyltetrahydrofolate + UDP-4-amino-4-deoxy-beta-L-arabinopyranose | Escherichia coli | ArnA is a key enzyme in the 4-amino-4-deoxy-L-arabinose-lipid A modification pathway. It is a bifunctional enzyme catalyzing the oxidative decarboxylation of UDP-glucuronic acid to the UDP-4''-ketopentose (UDP-beta-L-threo-pentapyranosyl-4''-ulose) and the N-10-formyltetrahydrofolate-dependent formylation of UDP-4-amino-4-deoxy-L-arabinose. The transformylase activity of the Escherichia coli ArnA is contained in its 300 N-terminal residues | 5,6,7,8-tetrahydrofolate + UDP-4-deoxy-4-formamido-beta-L-arabinopyranose | - |

The transformylase activity of the Escherichia coli ArnA is contained in its 300 N-terminal residues. A mechanism for the transformylation reaction is proposed, catalyzed by ArnA involving residues N102, H104, and D140 | Escherichia coli | 5,6,7,8-tetrahydrofolate + UDP-4-deoxy-4-formamido-beta-L-arabinopyranose | - |
