Sysname
3-deoxyoctulosonyl-lipopolysaccharide hydrolase
Reaction(IUBMB)
3-deoxyoctulosonyl-lipopolysaccharide + H2O = 3-deoxyoctulosonic acid + lipopolysaccharide [RN:R06054]
Reaction(KEGG)
R06054;
(other) R12219
Show
Substrate
3-deoxyoctulosonyl-lipopolysaccharide [CPD:C06744];
H2O [CPD:C00001]
Product
3-deoxyoctulosonic acid [CPD:C01187];
lipopolysaccharide [CPD:C00338]
Comment
Releases Kdo (alpha- and beta-linked 3-deoxy-D-manno-octulosonic acid) from different lipopolysaccharides, including Re-LPS from Escherichia coli and Salmonella, Rd-LPS from S. minnesota, and de-O-acyl-re-LPS. 4-Methylumbelliferyl-alpha-Kdo (alpha-Kdo-OMec) is also a substrate.
