IntEnz Enzyme Nomenclature


Accepted name:
(Kdo)3-lipid IVA (2-4) 3-deoxy-D-manno-octulosonic acid transferase
Other names:
Kdo transferase [ambiguous]
3-deoxy-D-manno-oct-2-ulosonic acid transferase
3-deoxy-manno-octulosonic acid transferase
Systematic name:
CMP-3-deoxy-D-manno-octulosonate:(KDO)3-lipid IVA 3-deoxy-D-manno-octulosonate transferase ((2→4) glycosidic bond-forming)



The enzyme from Chlamydia psittaci transfers four KDO residues to lipid A, forming a branched tetrasaccharide with the structure α-KDO-(2,8)-[α-KDO-(2,4)]-α-KDO-(2,4)-α-KDO (cf. EC [lipid IVA 3-deoxy-D-manno-octulosonic acid transferase], EC [(KDO)-lipid IVA 3-deoxy-D-manno-octulosonic acid transferase], and EC [(KDO)2-lipid IVA (2-8) 3-deoxy-D-manno-octulosonic acid transferase]).
