NOVELTY - Isolated nucleic acid molecule encoding a polypeptide capable of producing a triterpenoid hydrocarbon, where the polypeptide comprises: at least 15 contiguous amino acid residues of any one of SEQ ID NOs: 1-5 (comprising fully defined 29-55 amino acids, as given in the specification) or 20-29 (comprising fully defined 403-34 amino acids, as given in the specification); at least 70% sequence identity to any one of SEQ ID NOs: 1-5 or 20-29; or a functional fragment of SEQ ID NO: 29, is new.    USE - The isolated nucleic acid is useful to produce: triterpenoid hydrocarbon; and an intermediate of a biofuel, a bioplastic, a pharmaceutical, a food additive, an industrial chemical, a specialty chemical production (all claimed), a detergent, a fertilizer, a medicine, a paint, a plastic, a synthetic fiber or a synthetic rubber.    ADVANTAGE - The isolated nucleic acid produces triterpenoid hydrocarbon using the microorganism, resulting in less harmful effects on the environment than conventional methods of generating diesel fuel, thus greatly reduces the environmental impact associated with using coal and petroleum.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for:    (1) an isolated polypeptide capable of producing the triterpenoid hydrocarbon, where the polypeptide is encoded by the isolated nucleic acid molecule;    (2) a vector comprising the nucleic acid molecule;    (3) a recombinant non-human organism capable of producing the triterpenoid hydrocarbon, comprising the nucleic acid molecule or the vector;    (4) producing the triterpenoid hydrocarbon comprising growing the recombinant organism under conditions sufficient for the organism to produce the triterpenoid hydrocarbon;    (5) the triterpenoid hydrocarbon produced by the above method;    (6) producing an intermediate of a biofuel, a bioplastic, a pharmaceutical, a food additive, an industrial chemical or a specialty chemical production, comprising: growing the recombinant organism under conditions sufficient for the organism to produce the triterpenoid hydrocarbon; harvesting the triterpenoid hydrocarbon from the organism; and producing the intermediate from the triterpenoid hydrocarbon;    (7) the intermediate produced by the above method; and    (8) a vector deposited as V10/022706 or V10/022707.
