Enzymes

General function:
Involved in transferase activity, transferring pentosyl groups
Specific function:
Catalyzes the transfer of the L-Ara4N moiety of the glycolipid undecaprenyl phosphate-alpha-L-Ara4N to lipid A. The modified arabinose is attached to lipid A and is required for resistance to polymyxin and cationic antimicrobial peptides
Gene Name:
arnT
Locus Tag:
PA3556
Molecular weight:
61.7 kDa
Reactions
4-amino-4-deoxy-alpha-L-arabinopyranosyl di-trans,octa-cis-undecaprenyl phosphate + lipid IV(A) = lipid II(A) + di-trans,octa-cis-undecaprenyl phosphate.
General function:
Involved in transferase activity, transferring glycosyl groups
Specific function:
Heptose transfer to the lipopolysaccharide core. It transfers the innnermost heptose to [4'-P](3-deoxy-D-manno- octulosonic acid)2-IVA
Gene Name:
rfaC
Locus Tag:
PA5011
Molecular weight:
39.7 kDa
