CC -!- FUNCTION: Catalyzes the conversion of UDP-4-keto-arabinose (UDP-Ara4O)
CC to UDP-4-amino-4-deoxy-L-arabinose (UDP-L-Ara4N). The modified
CC arabinose is attached to lipid A and is required for resistance to
CC polymyxin and cationic antimicrobial peptides. {ECO:0000256|HAMAP-
CC Rule:MF_01167}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=2-oxoglutarate + UDP-4-amino-4-deoxy-beta-L-arabinose = L-
CC glutamate + UDP-beta-L-threo-pentopyranos-4-ulose;
CC Xref=Rhea:RHEA:24710, ChEBI:CHEBI:16810, ChEBI:CHEBI:29985,
CC ChEBI:CHEBI:58708, ChEBI:CHEBI:58710; EC=2.6.1.87;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_01167};
CC -!- COFACTOR:
CC Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_01167};
CC -!- PATHWAY: Bacterial outer membrane biogenesis; lipopolysaccharide
CC biosynthesis. {ECO:0000256|HAMAP-Rule:MF_01167}.
CC -!- PATHWAY: Nucleotide-sugar biosynthesis; UDP-4-deoxy-4-formamido-beta-L-
CC arabinose biosynthesis; UDP-4-deoxy-4-formamido-beta-L-arabinose from
CC UDP-alpha-D-glucuronate: step 2/3. {ECO:0000256|HAMAP-Rule:MF_01167}.
CC -!- SUBUNIT: Homodimer. {ECO:0000256|HAMAP-Rule:MF_01167}.
CC -!- SIMILARITY: Belongs to the DegT/DnrJ/EryC1 family. ArnB subfamily.
CC {ECO:0000256|HAMAP-Rule:MF_01167}.
