CC   -!- FUNCTION: Catalyzes the deformylation of 4-deoxy-4-formamido-L-
CC       arabinose-phosphoundecaprenol to 4-amino-4-deoxy-L-arabinose-
CC       phosphoundecaprenol. The modified arabinose is attached to lipid A and
CC       is required for resistance to polymyxin and cationic antimicrobial
CC       peptides. {ECO:0000255|HAMAP-Rule:MF_01870}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=4-deoxy-4-formamido-alpha-L-arabinopyranosyl di-trans,octa-
CC         cis-undecaprenyl phosphate + H2O = 4-amino-4-deoxy-alpha-L-
CC         arabinopyranosyl di-trans,octa-cis-undecaprenyl phosphate + formate;
CC         Xref=Rhea:RHEA:27734, ChEBI:CHEBI:15377, ChEBI:CHEBI:15740,
CC         ChEBI:CHEBI:58909, ChEBI:CHEBI:60463; EC=3.5.1.n3;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01870};
CC   -!- PATHWAY: Glycolipid biosynthesis; 4-amino-4-deoxy-alpha-L-arabinose
CC       undecaprenyl phosphate biosynthesis; 4-amino-4-deoxy-alpha-L-arabinose
CC       undecaprenyl phosphate from UDP-4-deoxy-4-formamido-beta-L-arabinose
CC       and undecaprenyl phosphate: step 2/2. {ECO:0000255|HAMAP-
CC       Rule:MF_01870}.
CC   -!- PATHWAY: Bacterial outer membrane biogenesis; lipopolysaccharide
CC       biosynthesis. {ECO:0000255|HAMAP-Rule:MF_01870}.
CC   -!- SIMILARITY: Belongs to the polysaccharide deacetylase family. ArnD
CC       deformylase subfamily. {ECO:0000255|HAMAP-Rule:MF_01870}.
