BL21∆serB E.coli srain大肠杆菌磷酸丝氨酸磷酸酶敲除株

To prevent possible enzymatic dephosphorylation of O-phospho-L-serine (Sep) in vivo, the gene encoding phosphoserine phosphatase (serB), which catalyzes the last step in serine biosynthesis, was deleted from Escherichia coli strain BL21. Markerless gene deletions were carried out using a λ-red and FLP recombinase-based gene knockout strategy.
