Abstract
We have localized the D108 thermosensitive (cts) repressor gene to a region of DNA approx. 600 base pairs (bp) in length by sub‐cloning an RsaI restriction endonuclease fragment (bp 200 to bp 802 from the left‐end of the D108 genome). We determined that the gene product from this fragment appears to be the same size (19 kDa) as that expressed from clones containing larger fragments of D108 DNA. Results from in vitro gel electrophoresis band‐retardation and in vivo immunity assays show that the sub‐cloned repressor appears to be fully functional.Keywords
