Chlorellaellipsoidea로 부터 polyphosphate phosphohydrolase의 분리, 정제 및 성질
Purification and properties of polyphosphate phosphohydrolase from chlorella ellipsoidea
초록
The presence of polyphosphate phosphohydrolase (PPPH) and tripolyphosphate phosphohydrolase (TPPH) in Chlorella ellipsoidea were confirmed from the cell-free extract of the algal cells and three forms of PPPH were isolated, purified, and measured Km-Vmax value and inhibitory effect by metal ions, respectively. PPPH was most active at pH7.2, whereas TPPH at pH 7.6. Both enzymes exhibited their maximum activity at
