Molecular dynamics study of the stabilities of consensus designed ankyrin repeat proteins.

Abstract excerpt

Two designed ankyrin repeat (AR) proteins (E3_5 and E3_19) are high homologous (with about 87% sequence identity) and their crystal structures have a Calpha atom-positional root-mean-square difference of about 0.14 nm. However, it was found that E3_5 is considerably more stable than E3_19 in guanidinium hydrochloride and thermal denaturation experiments. With the goal of providing insights into the various...
