Class of enzymes
Lipid IVA 3-deoxy-D-manno-octulosonic acid transferase (EC 2.4.99.12 , KDO transferase , waaA (gene) , kdtA (gene) , 3-deoxy-D-manno-oct-2-ulosonic acid transferase , 3-deoxy-manno-octulosonic acid transferase , lipid IVA KDO transferase ) is an enzyme with systematic name CMP-3-deoxy-D-manno-oct-2-ulosonate:lipid IVA 3-deoxy-D-manno-oct-2-ulosonate transferase .[ 1] [ 2] [ 3] [ 4] This enzyme catalyses the following chemical reaction
lipid IVA + CMP-alpha-Kdo
⇌ ⇌ -->
{\displaystyle \rightleftharpoons }
alpha-Kdo-(2->6)-lipid IVA + CMP
The bifunctional enzyme from Escherichia coli transfers two 3-deoxy-D-man no-oct-2-resonate residues to lipid IVA.
