CC -!- FUNCTION: Involved in lipopolysaccharide (LPS) biosynthesis. Catalyzes
CC the transfer of predominantly four 3-deoxy-D-manno-octulosonate (Kdo)
CC residues from CMP-Kdo to lipid IV(A), the tetraacyldisaccharide-1,4'-
CC bisphosphate precursor of lipid A. Thus generates the genus-specific
CC LPS epitope of Chlamydia, composed of the trisaccharide alpha-Kdo-
CC (2->8)-alpha-Kdo-(2->4)-alpha-Kdo. {ECO:0000269|PubMed:10951204,
CC ECO:0000269|PubMed:7523826, ECO:0000269|PubMed:7744029}.
