2.3.1.242	a palmitoleoyl-[acyl-carrier protein] + (3-deoxy-alpha-D-manno-oct-2-ulopyranosylonate)-(2->4)-(3-deoxy-alpha-D-manno-oct-2-ulopyranosylonate)-(2->6)-2-deoxy-2-[[(3R)-3-hydroxytetradecanoyl]amino]-3-O-[(3R)-3-hydroxytetradecanoyl]-4-O-phosphono-beta-D-glucopyranosyl-(1->6)-2-deoxy-3-O-[(3R)-3-hydroxytetradecanoyl]-2-[[(3R)-3-hydroxytetradecanoyl]amino]-1-O-phosphono-alpha-D-glucopyranose	the enzyme is involved in the formation of a cold-adapted lipid A. It transfers palmitoleate from palmitoleoyl-[acyl-carrier protein] to Kdo2-lipid IVA, which is also the acceptor for the lpxL-encoded lauroyl transferase. Palmitoleate is not present in lipid A isolated from Escherichia coli grown at 30°C or higher, but it comprises about 11% of the fatty acyl chains of lipid A in cells grown at 12°C. The appearance of palmitoleate at 12°C is accompanied by a decline in laurate from 18% to 5.5%. The palmitoleoyl transferase is induced more than 30fold upon cold shock. The replacement of laurate with palmitoleate in lipid A may reflect the desirability of maintaining the optimal outer membrane fluidity at 12°C
2.3.1.242	a palmitoleoyl-[acyl-carrier protein] + alpha-Kdo-(2->4)-alpha-Kdo-(2->6)-lipid IVA	Kdo i.e. 3-deoxy-D-manno-octulosonic acid. The enzyme is involved in lipid A acylation at low temperatures (21°C)
