The present invention relates to Aspergillus porphobilinogen synthases and isolated nucleic acid fragments comprising nucleic acid sequences encoding the porphobilinogen synthases as well as nucleic acid constructs, vectors, and recombinant host cells comprising the nucleic acid sequences. The invention also relates to methods of producing the porphobilinogen synthases.

The present invention relates to methods of producing hemoproteins comprising (a) introducing into a filamentous fungal cell, which is capable of producing the hemoprotein, (i) one or more first control sequences capable of directing the expression of a heme biosynthetic enzyme encoded by a first nucleic acid sequence endogenous to the filamentous fungal cell, wherein the one or more of the first control sequences are operably linked to the first nucleic acid sequence; and/or (ii) one or more copies of one or more second nucleic acid sequences encoding a heme biosynthetic enzyme; (b) cultivating the filamentous fungal cell in a nutrient medium suitable for production of the hemoprotein and the heme biosynthetic enzymes; and (c) recovering the hemoprotein from the nutrient medium of the filamentous fungal cell.

This invention relates to plant thioesterases, specifically plant acyl-ACP thioesterases having substantial activity on palmitoyl-ACP substrates. DNA constructs useful for the expression of a plant palmitoyl-ACP thioesterase in a plant seed cell are described. Such constructs will contain a DNA sequence encoding the plant palmitoyl-ACP thioesterase of interest under the control of regulatory elements capable of preferentially directing the expression of the plant palmitoyl-ACP thioesterase in seed tissue, as compared with other plant tissues, when such a construct is expressed in a transgenic plant. This invention also relates to methods of using a DNA sequence encoding a plant palmitoyl-ACP thioesterase for the modification of the proportion of free fatty acids produced in a plant seed cell. Plant palmitoyl-ACP thioesterase sequences exemplified herein include Cuphea, leek, mango and elm. Transgenic plants having increased levels of C16:0 fatty acids in their seeds as the result of expression of these palmitoyl-ACP thioesterase sequences are also provided.
