  • Lytic .beta.-1,3-glucanase gene
    Patent number: 5883244
    Abstract: The present invention relates to recombinant .beta.-1,3-glucanase essentially free of proteases. The enzyme is obtained through the use of a recombinant DNA expression vector which comprises a DNA sequence encoding the .beta.-1,3-glucanase gene or mutants and variants thereof placed under the control of an exogenous expression promoter, preferably a bacterial promoter. Also, the .beta.-1,3-glucanase gene may include sequences flanking the open reading frame of the native .beta.-1,3-glucanase gene. The present invention also relates to a microorganism transformed with a recombinant DNA expression vector comprising the .beta.-1,3-glucanase gene or mutants and variants thereof under the control of an exogenous expression promoter.

  • Prostaglandin receptor EP2
    Patent number: 5759789
    Abstract: A novel prostaglandin receptor has been identified and DNA encoding the receptor has been isolated, purified, sequenced and expressed in host cells. This DNA encoding the novel prostaglandin receptor and host cells expressing the receptor are used to identify modulators of the prostaglandin receptor.
