In various organisms, UDG goes by different names, such as b2580, JW2564, EC 3.2.2.27, DGU, UNG15, HIGM5, EC 3.2.2, HIGM4, and UNG2. Here, we delve into the E. coli UDG, examining its structure, function, and applications in molecular biology. Structure: The crystal structure of E. coli UDG has been extensively studied, revealing that it belongs to the uracil DNA glycosylase (UDG) superfamily. The E. coli UDG monomer has 229 amino acids with a molecular weight of 25 kDa. The protein has a beta-sheet-rich structure with an alpha-helix on one side and a groove on the other side that binds to DNA. The active site of E. coli UDG contains a conserved glutamic acid residue that acts as a catalytic base to facilitate the hydrolysis of the N-glycosidic bond between uracil and the sugar phosphate backbone. Function: E. coli UDG plays a critical role in maintaining the integrity of the genome by preventing the accumulation of mutations that can arise from the incorporation of uracil into DNA. Uracil in DNA can occur spontaneously from the deamination of cytosine or can be incorporated during DNA synthesis when dUTP is used instead of dTTP. Unrepaired uracil bases can lead to DNA damage and genomic instability, possibly resulting in cell death or disease. E. coli UDG specifically recognizes and removes uracil bases from DNA, creating an abasic site that is further processed by other repair enzymes.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"bhp-desc\"\u003e\n\u003ch3 style=\"color:#1a5c58;margin:12px 0 4px\"\u003eSpecifications\u003c\/h3\u003e\n\u003ctable style=\"width:100%;border-collapse:collapse;font-size:0.92em\"\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding:4px 8px;background:#e8f4f3;width:180px;font-weight:bold\"\u003ePurity\u003c\/th\u003e\n\u003ctd style=\"padding:4px 8px\"\u003eGreater than 97.0% as determined by SDS-PAGE.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding:4px 8px;background:#e8f4f3;width:180px;font-weight:bold\"\u003eFormulation\u003c\/th\u003e\n\u003ctd style=\"padding:4px 8px\"\u003eUNG protein solution (5U\/ul) containing 10mM Tris-HCl (25℃, pH 7.4), 50mM KCl, 0.1 mM EDTA, 1mM DTT, 0.1mg\/ml BSA \u0026amp; 50% glycerol.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding:4px 8px;background:#e8f4f3;width:180px;font-weight:bold\"\u003eStorage\u003c\/th\u003e\n\u003ctd style=\"padding:4px 8px\"\u003eStore at 4°C if entire vial will be used within 2-4 weeks.
