Experimental research has shown that the stability of the C-terminal hairpin of Protein G (GB1) increases with the number of tryptophan (Trp) residues. However, the increase in Trp residues also increase the folding time. To understand the roots of this behavior we performed extensive explicit water molecular dynamic (MD) simulations (~10 milliseconds total) on the GB1 hairpin and its Trp zipper mutants.
