SKU:: 052634
Molecular Weight:: 90.6
Purity:: ≥85% (SDS-PAGE)
Storage Conditions:: -20°C
Supplier:: United States Biological
Format:: Supplied as a lyophilized powder from 20mM Tris-HCl, 0.5M sodium chloride, pH 8.0, 6% trehalose. Reconstitute with sterile ddH2O to a concentration of 0.1-1mg/ml.
Extra Details:: Catalyzes two activities which are involved in the biotine biosynthesis: the conversion of dethiobiotin (DTB) to biotin by the insertion of a sulfur atom into dethiobiotin via a radical-based mechanism, and the transfer of the alpha-amino group from S-adenosyl-L-methionine (SAM) to 7-keto-8-aminopelargonic acid (KAPA) to form 7,8-diaminopelargonic acid (DAPA). Full length recombinant protein corresponding to aa1-748 from Bacteroides fragilis (strain ATCC 25285/DSM 2151/CCUG 4856/JCM 11019/NCTC 9343/Onslow) Biotin biosynthesis bifunctional protein BioAB, fused to 10X His-Tag at N-terminal and Myc-Tag at C-terminal, expressed in E. coli.
