Protein Properties: Binding Sites [edit]. A binding site is a position on a protein that binds to an incoming molecule that is smaller in size comparatively, called ligand. In proteins, binding sites are small pockets on the tertiary structure where ligands bind to it using weak forces (non-covalent bonding).
There are many different types of tRNA and each tRNA is recognised by a tRNA-activating enzyme. This enzyme binds a specific amino acid to the tRNA by using ATP as an energy source. The tRNA molecule has a specific structure. It contains double stranded sections (due to base pairing via hydrogen bonds) and loops.It has an anticodon loop which contains the anticodon and two other loops.ach enzyme will attach a specific amino acid to the tRNA which has the matching anticodon for that amino acid. When the amino acid binds to the tRNA molecule a high energy bond is created. The energy from this bond is used later on to bind the amino acids to the growing polypeptide chain during translation.
