Abstract: The present invention relates to recombinant DNA which encodes the BpmI restriction endonuclease as well as BpmI methyltransferase, expression of BpmI restriction endonuclease from E. coli cells containing the recombinant DNA. BpmI endonuclease is a fusion of two distinct elements with a possible structural domains of restriction-methylation-specificity (R-M-S). This domain organization is analogous to the type I restriction-modification system with three distinct subunits, restriction, methylation, and specificity (R, M, and S). Because BpmI is quite distinct to other type IIs restriction enzymes, it is proposed that BpmI belongs to a subgroup of type II restriction enzymes called type IIf (f stands for fusion of restriction-modification-specificity domains). The Type IIf group of restriction enzyme includes Eco57I, BpmI, GsuI, BseRI and some other restriction enzymes that cut downstream sequences at long distance, 10-20 bp downstream of recognition sequence, such as MmeI (N20/N18)).

Abstract: The present invention relates to recombinant DNA which encodes the NheI restriction endonuclease as well as NheI methyltransferase, expression of NheI restriction endonuclease from E. coli cells containing the recombinant DNA. An internal NdeI site in the nheIR gene was eliminated by a silent mutation. A new NdeI site was engineered at the start codon of nheIR gene. An NdeI-BamHI fragment containing nheIR gene was cloned into a T7 expression vector pAII17 and expressed in a premodified host ER2566 [pACYC-NheIM, pAII17-NheIR2]. The recombinant clone produces approximately 10 million units of NheI per gram of wet cells.

The material that is used for the diaphragm can be silicon nitride, or multiple layers including silicon nitride and other materials. The pressure sensor is intended to be used in high pressure applications, e.g. pressure is higher than 6000, 10,000 or 30,000 P.S.I.
