Shikimate and phenylalanine biosynthesis in the green lineage
The Plant Cell, Vol. 7, 907-919, July 1995 O American Society of Plant Physiologists The Shikimate Pathway: Early Steps in the Biosynthesis of... The shikimate pathway (shikimic acid pathway) is a seven step metabolic route used by bacteria, archaea, fungi, algae, some protozoan, and plants for the biosynthesis of folates and aromatic amino acids (phenylalanine, tyrosine, and tryptophan).
Shikimik acid pathway SlideShare
The shikimate pathway consists of seven enzymatic reactions whose end product chorismate is the precursor for the synthesis of the aromatic amino acids Phe, Tyr and Trp. In fungi and plants, chorismate is a precursor for many specialised metabolites (i.e. secondary metabolites) that play an important role in the plant's interaction with its environment. The shikimate pathway and aromatic …... apicomplexans, and plants. The plant shikimate pathway enzymes have similarities to prokaryote homologues and are largely active in chloroplasts, suggesting ancestry from the plastid progenitor genome. Toxoplasma gondii, which also possesses an alga-derived plastid organelle, encodes a shikimate pathway with similarities to ascomycete genes, including a ﬁve-enzyme pentafunctional …

THE SHIKIMATE PATHWAY: AROMATIC AMINO ACIDS AND PHENYLPROPANOIDS Shikimic acid and its role in the formation of aromatic amino acids, benzoic acids, and cinnamic acids is described, along with further modiﬁcations leading to lignans and lignin, phenylpropenes, and coumarins. Combinations of the shikimate pathway and the acetate pathway are responsible for the … vegetative propagation in plants pdf thesis pathways in plants. The biosynthesis of AAA from core primary metabolism initi-ates via the shikimate pathway, leading to the synthesis of cho-rismate (Fig. 2). Chorismate is the initial branch point metabolite in the synthesis of all three AAA (Fig. 2) and the wide range of aromatic secondary metabolites derived from it (Gilchrist and Kosuge, 1980; Herrmann, 1995). Hence, the shikimate
