(A) Unfolding transitions of the F47L mutant in a mixed urea/ TMAO cosolvent monitored by circular dichroism at 222 nm. Urea denaturation in increasing TMAO concentrations (from left to right at 0, 1.60, 1.88, 2.15, 2.50M TMAO); (B) Dependence of unfolding free energy on TMAO concentration for the F47L mutant; parameters are obtained by fitting urea unfolding curves in different TMA004F concentrations. The straight line is the result of linear regression to each parameter.
