Enzymes

General function:
Involved in biosynthetic process
Specific function:
Essential step in lipopolysaccharides biosynthesis. Acts at transfer of 3-deoxy-D-mono octulonic acid (KDO) from CMP-KDO to a tetraacyldisaccharide 1,4'-bisphosphate precursor of lipid A (lipid IVA). Transfers two molecules of KDO to lipid IVA. Degraded by FtsH; therefore FtsH regulates the addition of the sugar moiety of the LPS and thus the maturation of the LPS precursor
Gene Name:
waaA
Uniprot ID:
P0AC75
Molecular weight:
47291
General function:
Involved in transferase activity, transferring acyl groups
Specific function:
Acylates the intermediate (KDO)2-lipid IVA to form (KDO)2-(lauroyl)-lipid IVA. Has 10 fold selectivity for lauroyl- ACP over myristoyl-ACP
Gene Name:
htrB
Uniprot ID:
P0ACV0
Molecular weight:
35407
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
Uniprot ID:
P76473
Molecular weight:

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.
