  • Compositions and methods for the synthesis and assay of enkephalinase
    Patent number: 5780025
    Abstract: DNA isolates coding for enkephalinase and methods of obtaining such DNA are provided, together with expression systems for recombinant production of enkephalinase for use in therapeutic or diagnostic compositions. Enkephalinase assays are facilitated by novel enkephalinase substrates.
    Type: Grant
    Filed: October 12, 1993
    Date of Patent: July 14, 1998
    Assignee: Genentech, Inc.
    Inventors: Bernard Malfroy-Camine, Peter R. Schofield
  • Nodulation gene promoter
    Patent number: 5484718
    Abstract: The invention includes a consensus nucleotide sequence found in the promoter regions of those Rhizobium and Bradyrhizobium nodulation genes which are activated by chemical inducer(s) in legume exudate. A promoter comprising the consensus sequence is a legume exudate-inducible promoter. A recombinant gene comprising a structural gene and a legume exudate-inducible promoter is selectively expressed in the presence of legume exudate or chemical inducer(s) and a functional nodD gene. The consensus nucleotide sequence isATCCAYNNYGYRGATGNWYKYKATCSAAWCAATCRATTTTACCARWYYKNSRR whereN is A, G, C or TY is C or TR is A or GW is A or TK is G or T andS is C or G.
    Type: Grant

    Date of Patent: January 16, 1996
    Assignee: Mycogen Plant Science, Inc.
    Inventors: Peter R. Schofield, John M. Watson, Kieran F. Scott, Barry G. Rolfe, Michael A. Djordjevic, Peter L. Kuempel, Roger W. Innes
  • Compositions and methods for the synthesis and assay of a mammalian enkephalinase
    Patent number: 4960700
    Abstract: DNA isolates coding for enkephalinase and methods of obtaining such DNA are provided, together with expression systems for recombinant production of enkephalinase for use in therapeutic or diagnostic compositions. Enkephalinase assays are facilitated by novel enkephalinase substrates.
    Type: Grant
    Filed: January 12, 1987
    Date of Patent: October 2, 1990
    Assignee: Genentech, Inc.
    Inventors: Bernard Malfroy-Camine, Peter R. Schofield
  • Turbine blade for gas turbine engine
    Patent number: 4462754
    Abstract: The blade has an aerofoil portion (16) having a first (23), a second (24), a third (25) and a fourth (26) internal spanwise passage for cooling air arranged in chordwise succession with the first passage being at the leading edge wall (17) of the blade. The first and third passages are connected to respective a cooling air supplies (14A,14B) at the root end (11) of the blade. At the tip (28) of the blade the third passage is connected to the second passage to introduce air, warmed on passing through the third passage, into the second passage and ameliorate undue cooling of the internal walls (19,20) between the first, second and third passages. The third passage is also connected to the fourth passage for supply of cooling air to the trailing region of the blade. The second passage has outlets (24A) to the exterior of the blade whereby the flow through the second passage is controllable independently of the air supply to the fourth passage, i.e. to the trailing region of the blade.
