| Comments： | Restriction digests of the clone give the following sizes (kb): BamHI--uncut; EcoRI--4.4, 1.55, 0.35; PstI--6.0; HindIII--6.0. If the chimeric protein is degraded by proteases, the alkaline phosphatase becomes soluble in the periplasm and retains activity. The host chromosome contains an insertionally inactivated gene for the periplasmic protease htrA (degP), and thus shows reduced protease activity and increased stability of periplasmic proteins. pKS3 encodes a Tsr-alkaline phosphatase chimeric protein, with Tsr being N-terminal and anchoring the protein in the membrane. The alkaline phosphatase portion is exposed in the periplasm and retains activity. |
