IntEnz Enzyme Nomenclature


Accepted name:
(Kdo)-lipid IVA 3-deoxy-D-manno-octulosonic acid transferase
Other names:
Kdo transferase
3-deoxy-D-manno-oct-2-ulosonic acid transferase
3-deoxy-manno-octulosonic acid transferase
Systematic name:
CMP-3-deoxy-D-manno-octulosonate:(Kdo)-lipid IVA 3-deoxy-D-manno-octulosonate transferase



The bifunctional enzyme from Escherichia coli transfers two 3-deoxy-D-manno-octulosonate residues to lipid IVA (cf. EC [lipid IVA 3-deoxy-D-manno-octulosonic acid transferase]) [1]. The enzymes from Chlamydia transfer three or more 3-deoxy-D-manno-octulosonate residues and generate genus-specific epitopes [4].
