case <OC:Escherichia>
FUNCTIONCatalyzes the transfer of laurate from lauroyl-[acyl-carrier- protein] (ACP) to Kdo(2)-lipid IV(A) to form Kdo(2)-(lauroyl)-lipid IV(A).
CATALYTIC ACTIVITY Reaction=alpha-Kdo-(2->4)-alpha-Kdo-(2->6)-lipid IVA (E. coli) + dodecanoyl-[ACP] = alpha-Kdo-(2->4)-alpha-Kdo-(2->6)-(dodecanoyl)- lipid IVA (E. coli) + holo-[ACP]; Xref=Rhea:RHEA:28442, Rhea:RHEA- COMP:9644, Rhea:RHEA-COMP:9685, ChEBI:CHEBI:60365, ChEBI:CHEBI:61524, ChEBI:CHEBI:64479, ChEBI:CHEBI:65264; EC=;
FUNCTIONCatalyzes the transfer of an acyl chain from an acyl-[acyl- carrier-protein] (ACP) to a Kdo(2)-lipid IV(A) to form a Kdo(2)-(acyl)- lipid IV(A).
CATALYTIC ACTIVITY Reaction=a fatty acyl-[ACP] + an alpha-Kdo-(2->4)-alpha-Kdo-(2->6)- lipid IVA = an alpha-Kdo-(2->4)-alpha-Kdo-(2->6)-(acyl)-lipid IVA + holo-[ACP]; Xref=Rhea:RHEA:69396, Rhea:RHEA-COMP:9685, Rhea:RHEA- COMP:14125, ChEBI:CHEBI:64479, ChEBI:CHEBI:138651, ChEBI:CHEBI:176429, ChEBI:CHEBI:176430; EC=;
