Plastidic aspartate aminotransferases and the biosynthesis of essential amino acids in plants.
In the chloroplasts and in non-green plastids of plants, aspartate is the precursor for the biosynthesis of different amino acids and derived metabolites that play distinct and important roles in plant growth, reproduction, development or defence. Aspartate biosynthesis is mediated by the enzyme aspartate aminotransferase (EC 2.6.1.1), which catalyses the reversible transamination between gluta...
متن کاملComparison of Essential and Non Essential Amino Acids in the Microbial Protein of Pleurotus Florida from the Lignocellulosic Wastes
Introduction: Cereal straws contain Cellulose, Hemicelluloses and Lignin and are most available renewable biopolymers. White rot fungi is used to convert these wastes into microbial protein. Pleurotus Florida are having the most delignification ability amongst other micro-organisms. We determined the amounts of protein, essential and non essential amino acids of the produced microbial protein f...
متن کاملBiosynthesis of 'essential' amino acids by scleractinian corals.
Animals rely on their diet for amino acids that they are incapable either of synthesizing or of synthesizing in sufficient quantities to meet metabolic needs. These are the so-called 'essential amino acids'. This set of amino acids is similar among the vertebrates and many of the invertebrates. Previously, no information was available for amino acid synthesis by the most primitive invertebrates...

متن کاملPrimary structures of aspartate aminotransferases.
three residues seems to be common to all the serine enzymes and has become known as the ‘charge-relay system’. Its function is to transfer a negative (or partial negative) charge from the aspartic acid residue to the oxygen atom of the hydroxy group of serine. This obviously increases the nucleophilicity of the serine, but the important point is that the charge is developed in the absence of bu...
