Threonine (symbol Thr or T) [2] is an amino acid that is used in the biosynthesis of proteins. It contains an α-amino group (which is in the protonated −NH + 3 form when dissolved in water), a carboxyl group (which is in the deprotonated −COO − form when dissolved in water), and a side chain containing a hydroxyl group , making it a ...
This aspartate pathway is present in plants and bacteria, allowing them to synthesize lysine, methionine, and threonine. This pathway is not present in humans or other animals, however. The lack of this pathway means that humans need to take in these amino acids through their diet, which is why they are called essential amino acids. [6] [7]
Cyclothiazomycin C has a lysine in place of the second threonine residue found in cyclothiazomycin A and a serine residue in place of the third threonine residue, resulting in a dehydroalanine instead of the dehydrohomoalanine observed in cyclothiazomycin A. [6] The cyclothiazomycin family of antibiotics includes cyclothiazomycins A, B, and C.
O-linked glycosylation is the attachment of a sugar molecule to the oxygen atom of serine (Ser) or threonine (Thr) residues in a protein. O-glycosylation is a post-translational modification that occurs after the protein has been synthesised.
Foods that reduce inflammation include fatty fish, tea, walnuts, and more. Here, a dietitian explains the best anti-inflammatory foods to eat.
Aspartate can be converted into lysine, asparagine, methionine and threonine. Threonine also gives rise to isoleucine. This diagram shows the biosynthesis (anabolism) of amino acids aspartate, asparagine, threonine, methionine, lysine from the precursor oxaloacetate.
