  • 产品描述：

    The preparation of Recombinant Human KMO protein included 3 main steps: construct the expression vector, expression of protein of interest, and protein purification. Every step was performed under a strict QC system so that we got the premium protein. This KMO was expressed in E.coli at and fused with N-terminal 6xHis-SUMO tag. According to SDS-PAGE, the purity turns out to be 90%+.

    kynurenine 3-monooxygenase (KMO) functions as a pivotal enzyme in the main branch of the enzymatic cascade because it generates several toxic metabolites, including 3-hydroxykynurenine and quinolinic acid, which are responsible for neurodegenerative and inflammatory disorders. In recent years, researchers first revealed a novel enzymatic activity independent function of KMO in triple negative breast cancer (TNBC). Specifically, the findings suggested a positive correlation between the increased expression of KMO in breast cancer and TNBC and metastasis and recurrence. Besides, the contribution of KMO expression to the malignant phenotype of TNBC cells, particularly cancer stem cell (CSC) properties, but which leads to increased expression of pluripotent genes such as Nanog, Oct4, and Sox2.

  • 功能：
    Catalyzes the hydroxylation of L-kynurenine (L-Kyn) to form 3-hydroxy-L-kynurenine (L-3OHKyn). Required for synthesis of quinolinic acid, a neurotoxic NMDA receptor antagonist and potential endogenous inhibitor of NMDA receptor signaling in axonal targeting, synaptogenesis and apoptosis during brain development. Quinolinic acid may also affect NMDA receptor signaling in pancreatic beta cells, osteoblasts, myocardial cells, and the gastrointestinal tract (Probable).
