4.D.1.1.13
Glycosyltransferase (Undecaprenyl-phosphate 4-deoxy-4-formamido-L-arabinose transferase) of 322 aas with 2-3 C-terminal TMSs, ArnC. Catalyzes the transfer of 4-deoxy-4-formamido-L-arabinose from UDP to undecaprenyl phosphate. The modified arabinose is attached to lipid A and is required for resistance to polymyxin and cationic antimicrobial peptides (Breazeale et al. 2002).  This protein does not catalyze transport and is homologous to other enzymes in the GT2 family only in the N-terminal cytoplasmic glycosyl transferase domain.
