The invention relates to compositions and methods, including polynucleotide sequences, amino acid sequences, recombinant host cells and recombinant host cell cultures engineered to produce fatty acid derivative compositions comprising fatty acids, fatty alcohols, fatty aldehydes, fatty esters, alkanes, terminal olefins, internal olefins or ketones. The fatty acid derivative composition is produced extracellularly with a higher titer, yield or productivity than the corresponding wild type or non-engineered host cell. 151.-. (canceled)52. A recombinant host cell comprising a decreased activity of a phosphoenolpyruvate carboxylase (ppc) polypeptide , wherein said recombinant host cell produces a fatty acid derivative composition at a higher titer , yield or productivity than a corresponding wild type host cell when cultured in a medium containing a carbon source under conditions effective to decrease expression of said ppc polypeptide.53. A cell culture comprising the recombinant host cell according to .54. The cell culture of claim 52 , wherein said cell culture comprises a fatty acid derivative composition.55. The cell culture of claim 54 , wherein the fatty acid derivative composition comprises at least one fatty acid derivative selected from the group consisting of fatty acid claim 54 , a fatty ester claim 54 , a fatty alcohol claim 54 , a fatty aldehyde claim 54 , an alkane claim 54 , a terminal olefin claim 54 , an internal olefin claim 54 , and a ketone.56. The cell culture of claim 53 , wherein the fatty acid derivative isa) a C6, C8, C10, C12, C13, C14, C15, C16, C17, or C18 fatty acid derivative, orb) a C10:1, C12:1, C14:1, C16:1, or C18:1 unsaturated fatty acid derivative.57. The cell culture of claim 54 , wherein the fatty acid derivative composition comprises:a) one or more of C8, C10, C12, C14, C16, and C18 fatty acid derivatives,b) fatty acids,c) fatty aldehydes,d) fatty alcohols,e) fatty esters,f) alkanes,g) terminal olefins,h) internal olefins, ori) ...
