UDP-4-amino-4-deoxy-L-arabinose formyltransferase ( EC 2.1.2.13, UDP-L-Ara4N formyltransferase, ArnAFT) is an enzyme with systematic name 10-formyltetrahydrofolate:UDP-4-amino-4-deoxy-beta-L-arabinose N-formyltransferase. [1] [2] [3] [4] [5] This enzyme catalyses the following chemical reaction

10-formyltetrahydrofolate + UDP-4-amino-4-deoxy-beta-L-arabinopyranose 5,6,7,8-tetrahydrofolate + UDP-4-deoxy-4-formamido-beta-L-arabinopyranose

The activity is part of a bifunctional enzyme that also performs the EC 1.1.1.305 reaction.
