    摘要: The present invention provides for novel vector constructs comprising an origin of replication; a nucleotide sequence encoding an intein, the nucleotide sequence having a unique restriction enzyme site, critical amino acid residues located at the splice junctions of the intein, the intein inserted into a nucleotide sequence encoding a selectable marker; and a nucleotide sequence encoding suitable regulatory elements so as to effect expression of the vector construct in a suitable host cell. The vector constructs of the present invention may contain a DNA of interest cloned into a unique restriction site of the intein, and may be used as a vaccine alone or transformed into a vaccine vector. The vector constructs of this invention may further be used in methods of selecting translated open reading frames or genes, leading to the identification of potentially protective antigens of pathogenic organisms.

    摘要: Recombinant mycobacterial vaccine vehicles capable of expressing DNA of interest which encodes at least one protein antigen for at least one pathogen against which an immune response is desired and which can be incorporated into the mycobacteria or stably integrated into the mycobacterial genome. The vaccine vehicles are useful for administration to mammalian hosts for purposes of immunization. A recombinant vector which replicates in E. coli but not in mycobacteria is also disclosed. The recombinant vector includes 1) a mycobacterial gene or portions thereof, necessary for recombination with homologous sequences in the genome of mycobacteria transformed with the recombinant plasmid; 2) all or a portion of a gene which encodes a polypeptide or protein whose expression is desired in mycobacteria transformed with the recombinant plasmid; 3) DNA sequences necessary for replication and selection in E coli; and 4) DNA sequences necessary for selection in mycobacteria (e.g., drug resistance). The present invention also relates to two types of recombinant vectors useful in introducing DNA of interest into mycobacteria, where it is expressed. One type of vector is a recombinant phasmid capable of replicating as a plasmid in E. coli and of lysogenizing a mycobacterial host. The other type of vector is a recombinant plasmid which can be introduced into mycobacteria, where it is stably maintained extrachromosomally.
