Glycogen synthase 1 Gene and Recombinant Vector Comprising the Gene and Host Cell Transformed with the Vector and Manipulation of Fatty Acid Composition and Contents via Glycogen Synthase 1-Defective Cyanobacterium Synechocystis PCC 6803

摘要

The present invention relates to a cyanobacteria total lipid content and composition control, and more particularly, cyanobacteria Cine Cauchy seutiseu (. Synechocystis sp) PCC 6803 from glycogen synthase 1 (Glycogen synthase 1; EC = 2.4.1.21) gene coding for the glgA1 (Locus name: sll0945) and , wherein the recombinant vector containing the gene, and a host cell transformed with the recombinant vector, to control the cyanobacteria glgA1 gene expression in cine Cauchy seutiseu relates to a method for controlling growth and composition of lipid content . These transformed strains according to the invention nor to use the carbon fixed by photosynthesis in water assimilation glycogen biosynthesis pathway, so that the results show the alternate path is significantly increased fatty acid production characteristics, for the production of bio-diesel photosynthetic algae Metabolic engineering is how to switch to biomass.
