  • Heat-stable prolylendopeptidase
    Patent number: 6284511
    Abstract: The present invention relates to the field of biotechnology and concerns heat-stable prolylendopeptidase, recombinant DNA coding for heat-stable prolylendopeptidase, and processes for the production of heat-stable prolylendopeptidase and of recombinant DNA coding therefor, a host transformed with said recombinant DNA and a process for the production of said transformed host.

  • DNA molecule encoding prokaryotic prolylendopeptidase
    Patent number: 5521081
    Abstract: The invention concerns DNA encoding prolylendopeptidase, hybrid vectors containing such DNA, transformed hosts capable of expressing prolylendopeptidase, a process for the production of prolylendopeptidase including the steps of: culturing a host organism transformed with an expression vector including a DNA coding for prolylendopeptidase and optionally, recovering the produced prolylendopeptidase; and a process for the production of a C-terminal amidated peptide from two precursors, including the steps of: placing the two precursors in contact with a prolylendopeptidase in a medium to convert the precursor peptides to the C-terminal amidated peptide, and recovering the resulting C-terminal amidated peptide.
