With a side chain consisting of an episilon-amino group, FTP identify this amino acid that, like histidine and arginine, has a basic side chain.
In bacteria, it modifies O2 of cytidine in the wobble position of isoleucine tRNA. The first step in its degradation in the liver involves the formation of an adduct with alpha-ketoglutarate known as saccharopine. In collagen, crosslinks can be formed by this amino acid and its hydroxylated derivative. It is the substrate for ubiquitin ligase and for histone acetyltransferases. In class I aldolases, this amino acid's side chain reacts with the enzyme substrate to make a Schiff base. With a side chain consisting of an episilon-amino group, FTP identify this amino acid that, like histidine and arginine, has a basic side chain.
