Mutant delta 5 desaturases, having the ability to convert dihomo-gamma-linolenic acid [DGLA; 20:3 omega-6] to arachidonic acid [ARA; 20:4 omega-6] and/or eicosatetraenoic acid [ETA; 20:4 omega-3] to eicosapentaenoic acid [EPA; 20:5 omega-3] and possessing at least one mutation within the HPGG (SEQ ID NO:7) motif of the cytochome b5-like domain and at least one mutation within the HDASH (SEQ ID NO:8) motif are disclosed. Isolated nucleic acid fragments and recombinant constructs comprising such fragments encoding delta 5 desaturases, along with a method of making long chain polyunsaturated fatty acids ["PUFAs"], are also disclosed.
