WebMar 1, 2010 · Proteins fold into a functional shape. A protein starts off in the cell as a long chain of, on average, 300 building blocks called amino acids. There are 22 different types of amino acids, and their ordering determines how the protein chain will fold upon itself. When folding, two types of structures usually form first.

WebA single 3′-terminal C residue can reduce RNase T action by more than 100-fold, and two terminal C residues essentially stop the enzyme. RNase T prefers a substrate with a CCAN, especially CCAA, sequence at the 3′ end (Zuo and Deutscher, 2002c). This makes RNase T well suited for tRNA maturation while preventing over-digestion of the CCA end.
