    Avi-tag Biotinylated

    E. coli biotin ligase (BirA) is highly specific in covalently attaching biotin to the 15 amino acid AviTag peptide. This recombinant protein was biotinylated in vivo by AviTag-BirA technology, which method is BriA catalyzes amide linkage between the biotin and the specific lysine of the AviTag.

靶点详情

  • 功能：
    Plays an important role in nitrogen catabolite repression. Down-regulates the expression of many genes involved in nitrogen utilization by inhibiting the GATA transcriptional activators GLN3 and GAT1. Under good nitrogen conditions, binds to the phosphorylated forms of GLN3 and GAT1 and sequesters them in the cytoplasm, preventing transcription of genes expressed upon nitrogen limitation. Is also an atypical glutaredoxin without a catalytical cysteine residue. Has glutathione peroxidase and thiol:disulfide oxidoreductase activities in both native and fibrillar form. Also shows insulin disulfide reductase and dehydroascorbic acid reductase (DHAR) actvites.

    2. study found that, in addition to Sis1,[URE3-1] is specifically dependent upon Swa2; data suggest that prion-chaperone specificity arises from the Swa2 TPR domain and supports a model where Swa2 acts through Hsp70, most likely to provide additional access points for Hsp104 to promote prion template generation PMID: 26031938
    3. Proteasomal degradation of Ure2p yields amyloidogenic N-terminal peptides and a C-terminal resistant fragment. In contrast to Sup35p, fibrillar Ure2p resists proteasomal degradation. PMID: 26115123

    17. Ure2 protects Saccharomyces cerevisiae from heavy metal ion and oxidative cellular damage. PMID: 15806612
    18. Local area electron diffraction and X-ray diffraction from partially aligned specimens showed that the 4.7A reflection is meridional and therefore the underlying structure is cross-beta. PMID: 15866740

    29. analysis of glutathione transferase activity of the yeast prion protein Ure2 PMID: 18845158
