Lysidine (nucleoside)
Lysidine is an uncommon nucleoside, rarely seen outside of tRNA. It is a derivative of cytidine in which the carbonyl is replaced by the amino acid lysine. The third position in the anti-codon of the Isoleucine-specific tRNA, is typically changed from a cytidine which would pair with guanosine to a lysidine which will base pair with adenosine Adenosine (symbol A) is an organic compound that occurs widely in nature in the form of diverse derivatives. The molecule consists of an adenine attached to a ribose via a β-N9-glycosidic bond. Adenosine is one of the four nucleoside buildin .... Uridine could not be used at this position even though it is a conventional partner for adenosine since it will also " wobble base pair" with guanosine. So lysidine allows better translation fidelity. Lysidine is denoted as L or k2C (lysine bound to C2 atom of cytidine). : References {{reflist Nucleosides Pyrimidines Hydroxymethyl compounds ...
