| In this study, heat shock protein, Hspa5 was cloned, expressed and purified subsequently confirmed that it interacted with the tyrosinase (TYR) in vitro. Then, using the crystal structure of the homologous protein from the bacteria as a template, a homology model of human TYR was constructed. This model was further applied to investigate the molecular docking with Hspa5. The model showed that the interaction between the TYR and Hspa5 was mainly maintained by some hydrogen bonds in a quite low energy state. The results indicated that TYR was protected in different denaturation conditions by Hspa5. It was concluded that Hspa5 served as a molecular chaperone of TYR, which could help to better understand the molecule regulation mechanism of TRY in many kinds... |
