By this invention, nucleic acid sequences encoding for enzymes with diacylglycerol acyltransferase (DAGAT) activity are provided, wherein said DAGAT is active in the formation of triacylglycerol from fatty acyl-CoA and sn1,2 diacylglycerol substrates. Of special interest are nucleic acid sequences from jojoba which encode a protein capable of producing wax esters from fatty alcohol and fatty acyl substrates, as well as producing triacylglycerol from sn1,2 diacylglycerol and fatty acid substrates. Also of interest are sequences related to the jojoba embryo wax synthase from Arabidopsis. Also considered are amino acid and nucleic acid sequences endocing DAGAT proteins and the use of such sequences to provide transgenic host cells capable of producing modified triacylglycerol compositions. |
