- acil-[acil-nosilac protein] + malonil-[acil-nosilac protein] 3-oksoacil-[acil-nosilac protein] + CO2 + [acil-nosilac protein]
Ovaj enzim je odgovoran za produžavanje lanca pri biosintezi disociranih (tip II) masnih kiselina, i.e. adicija dva C atoma na masno kiselinski lanac. Escherichia coli mutanti kojima nedostaje ovaj enzim su deficitarni u nezasićenim masnim kiselinama.
