US 5,510,255 A · Plant fatty acid synthases

Abstract

By this invention, compositions and methods of use related to .beta.-ketoacyl-ACP synthase, hereinafter also referred to as "synthase", are provided. Also of interest are methods and compositions of amino acid and nucleic acid sequences related to biologically active plant synthase(s). In particular, synthase protein preparations which have relatively high turnover (specific activity) are of interest for use in a variety of applications, in vitro and in vivo. Especially, protein preparations having synthase I and/or synthase II activities are contemplated hereunder. Synthase activities are distinguished by the preferential activity towards longer and shorter acyl-ACPs. Protein preparations having preferential activity towards shorter chain length acyl-ACPs are synthase I-type. Synthases having preferential activity towards longer chain length acyl-ACPs are synthase II-type. Of special interest are synthases obtainable from Ricinus communis.

A method of making mRNA encoding a plant synthase protein in an oilseed crop plant comprising:

growing a plant cell having integrated in its genome a DNA construct, said construct comprising in the 5' to 3' direction of transcription, a transcriptional regulatory region functional in said plant cell and a plant synthase factor A or synthase factor B protein encoding sequence oriented for transcription of a sense sequence under conditions which will permit the transcription of said plant synthase protein encoding sequence.
