title: Shotgun cloning and characterization of the thymidylate synthase-encoding gene from Mycobacterium bovis BCG.
abstract: The shotgun cloning of a Mycobacterium bovis BCG (BCG) genome into pBluescript SK (+) successfully yielded a 0.9 kbp fragment, confirming the ability of Escherichia coli thyA mutant MH2702 to grow in a thymine-depleted medium. This DNA fragment contained a gene homologous to the thymidylate synthase (TS)-encoding genes (thyA) of other organisms. An inverted repeat sequence and open reading frame (ORF) were observed at the upstream region of the thyA. A computer analysis revealed that the protein encoded by this ORF possessed a structure unique for a DNA binding protein.
