Fig. 4. The crystal structure and thermal stability of HuHF and EP-inserted mutant (HuHF-∇EP). (a) The crystal structure of HuHF-∇EP viewed down the 4-fold channels (PDB ID: 6J4A). (b) The body-centered-cubic (BCC) packing arrangement of HuHF-∇EP crystals. (c and d) DSC curves of native HuHF (c) and its mutant HuHF-∇EP (d), at scan rate of 10 °C min−1.
