We succeeded in hyperproduction of Bacillus thuringiensis phosphatidylinositol-specific phospholipase C (PIPLC), using a Bacillus brevis 47 expression system. The recombinant B. thuringiensis PIPLC was expressed under the control of the middle wall protein gene promoter in B. brevis expression vector pNU211. A large amount of recombinant PIPLC (0.4 g per liter culture) was secreted into the medium as a mature enzyme, and the enzymatic properties of purified recombinant PIPLC were similar to those of the enzyme from wild-type B. thuringiensis. This system provides a useful approach to the three-dimensional structure-function relationship of PIPLC.

D005822	Genetic Vectors	DNA molecules capable of autonomous replication within a host cell and into which other DNA sequences can be inserted and thus amplified. Many are derived from PLASMIDS; BACTERIOPHAGES; or VIRUSES. They are used for transporting foreign genes into recipient cells. Genetic vectors possess a functional replicator site and contain GENETIC MARKERS to facilitate their selective recognition.

D001407	Bacillus	A genus of BACILLACEAE that are spore-forming, rod-shaped cells. Most species are saprophytic soil forms with only a few species being pathogenic.	Bacillus bacterium
D001413	Bacillus thuringiensis	A species of gram-positive bacteria which may be pathogenic for certain insects. It is used for the biological control of the Gypsy moth.	Bacilan,Dipel,Thuricide
D043265	Phosphatidylinositol Diacylglycerol-Lyase	A phosphorus-oxygen lyase found primarily in BACTERIA. The enzyme catalyzes the cleavage of a phosphoester linkage in 1-phosphatidyl-1D-myo-inositol to form 1D-myo-inositol 1,2-cyclic phosphate and diacylglycerol. The enzyme was formerly classified as a phosphoric diester hydrolase (EC 3.1.4.10) and is often referred to as a TYPE C PHOSPHOLIPASES. However it is now known that a cyclic phosphate is the final product of this enzyme and that water does not enter into the reaction.	1-Phosphatidylinositol Phosphodiesterase,Monophosphatidylinositol Phosphodiesterase,1 Phosphatidylinositol Phosphodiesterase,Diacylglycerol-Lyase, Phosphatidylinositol,Phosphatidylinositol Diacylglycerol Lyase,Phosphodiesterase, 1-Phosphatidylinositol,Phosphodiesterase, Monophosphatidylinositol
