Acyl-ACP wax ester synthases

A recombinant host cell genetically engineered for the production of fatty acid esters from acyl-ACP, wherein the recombinant host cell comprises a non-native nucleic acid sequence that encodes (1) an acyl-ACP wax ester synthase having a sequence identity of at least 85% to a polypeptide selected from the group consisting of SEQ ID NO:

• 19, SEQ ID NO:
• 21, SEQ ID NO:
• 23, SEQ ID NO:
• 25, SEQ ID NO:
• 27, SEQ ID NO:
• 29, SEQ ID NO:
• 31, SEQ ID NO:
• 33, SEQ ID NO:
• 35, SEQ ID NO:
• 37, SEQ ID NO:
• 39, SEQ ID NO:
• 41, and SEQ ID NO:
• 43 and (2) a non-native nucleic acid sequence that encodes an alcohol-forming acyl-ACP reductase having a sequence identity of at least 85% to a polypeptide selected from the group consisting of SEQ ID NO:
• 2, SEQ ID NO:
• 4, SEQ ID NO:
• 6, SEQ ID NO:
• 8, and SEQ ID NO:
• 10, wherein each non-native nucleic acid sequence is operably linked to a promoter, and wherein at least one of the non-native nucleic acids is heterologous relative to the host cell or to the promoter to which the non-native nucleic acid sequence is operably linked, and further wherein the recombinant host cell does not express one or more of:
• a) an exogenous acyl-ACP thioesterase;
• b) an exogenous acyl-CoA thioesterase;
• and
• c) an exogenous acyl-CoA synthetase.
