Maltose-binding protein (MBP) is a free protein in the E. coli K12 strain, encoded by the malE gene with a molecular weight of 42 kDa, which is a member of the uptake and breakdown of maltose pathway in E. coli. The most outstanding feature of the MBP label is its strong and highly soluble ability. It is mainly manifested in two aspects: wide range of dissolution and high efficiency. Another important reason for the widespread application of MBP tag is its ability to achieve monopolar purification by specifically binding tags and amylose and eluting under non-denaturing conditions.

Usage and Biology
Maltose-binding protein (MBP) is a free protein in the E. coli K12 strain, encoded by the malE gene with a molecular weight of 42 kDa, which is a member of the uptake and breakdown of maltose pathway in E. coli. The most outstanding feature of the MBP label is its strong and highly soluble ability. It is mainly manifested in two aspects: wide range of dissolution and high efficiency. Another important reason for the widespread application of MBP tag is its ability to achieve monopolar purification by specifically binding tags and amylose and eluting under non-denaturing conditions. In addition, fused MBP to either the N terminus or the C terminus was prosoluble. A commercial MBP fusion tag vector is already available to accommodate the research needs.
We add a solubilization-promoting tag at the N-end of the P450 enzyme, and in the selected six solubilization-promoting tags (SUMO, GST, MBP, TF, TRX, Nus), MBP and TF can significantly improve the solubility of Olep protein, but the enzyme activity of Olep is reduced, and the catalytic efficiency is lower than strain without solubilizing tag.
