CGSC Strain#: 7511
Strain Designation: CAG5054      Source of Strain: C.A. Gross
Sex: Hfr    Point of Origin#: 44   Map Position: 46.69   Direction of Marker Transfer: Counterclockwise
Chromosomal Markers: λ^-, trpC83::Tn10, relA1, spoT1, thiE1
Strain Comments:

• trpC83::Tn10-- PCR analysis by Nichols et al. 1998 placed this insertion in the trpC rather than trpB gene (at nucleotide 1,317,596 or 28.401 min.)
• spoT1-- In addition to the 6bp insertion, there is a C to T transition resulting in an H257Y substitution.
• thiE1 was formerly called thi-1
• trpC83::Tn10 was formerly called trpB83::Tn10
• = tetracycline resistant
