ArnC is involved in the modification of lipid A phosphates with aminoarabinose that is required for polymyxin B and cationic antimicrobial peptide resistance. UDP-beta-4-deoxy-4-formamido-L-arabinose is the sugar donor. The arnBCADTEF operon promoter region binds FNR and arnBCADTEF expression is repressed by FNR (Federowicz, 2014). basRS regulon.
