일반 설명

Glutaminase is an amidohydrolase. It has the catalytic domain in the N-terminal and the C-terminal extension possesses STAS domain.

애플리케이션

Glutaminase from E.coli has been used:
  • for the determination of glutamine from the cerebral cortex tissue extract
  • for immobilization on aminopropylsilylated controlled pore glass (CPG) for determination of glutamine
  • in combination with acivicin in in vitro melanoma cells and MCF-7 and OAW-42 cells for cell proliferation and invasiveness assay.

생화학적/생리학적 작용

Glutaminase catalyzes the conversion of glutamine to glutamate.
Glutaminase from Escherichia coli along with acivicin, a glutamine analog regulates proliferation and invasiveness of cancer cells. Bacterial glutaminase is implicated in increasing the life span of cancer patients by lowering the tumor burden.
