Construction of a CaHPO4-PGUS1 hybrid nanoflower through protein-inorganic self-assembly, and its application

Tian Jiang, Yuhui Hou, Tengjiang Zhang, Xudong Feng, Chun Li

Frontiers of Chemical Science and Engineering 2019, Volume 13, Issue 3,   Pages 554-562 doi: 10.1007/s11705-019-1834-z

Abstract: In this study, a facile method was established to prepare a CaHPO -PGUS1 hybrid nanoflower for enzymeimmobilization, based on protein-inorganic hybrid self-assembly.Under optimal conditions, 1.2 mg of a CaHPO -PGUS1 hybrid nanoflower precipitate with 71.2% immobilizationencapsulated in the CaHPO -PGUS1 hybrid nanoflower.Moreover, the thermostability of the CaHPO -PGUS1 hybrid nanoflower at 55°C was improved, and its half-life
