    摘要: The present invention provides isolated and recombinant avian nucleic acid molecules comprising at least one avian MAR and an avian nucleic acid sequence encoding an ovalbumin transcriptional regulatory region. The isolated nucleic acid of the present invention is useful for reducing chromosomal positional effects upon the transcription of a transgene operably linked to the ovalbumin transcriptional regulatory region and transfected into a recipient avian cell The recombinant nucleic cid molecules of the present invention may further comprise a polyadenylation signal sequence or an avian 3' domain, and optionally, an internal ribosome entry site for expression of an operably linked heterologous nucleic acid insert in a transfected avian cell.

    摘要: A method for identifying active site inhibitors of scission enzyme that cleaves the backbones or side groups of peptides, and for using the resultant inactivators to inhibit the target scission enzyme. Kinetic assays are employed to identify peptide substrates that tightly bind to the active site of the target protease but that are not easily cleaved. These noncleavable but tightly binding substrates are optionally structurally modified to yield inhibitory compounds with optimized properties. Additionally these substrates exhibit apparent specificity for a transition state or ground state configuration of the protease.
