CGSC Strain#: 7058
Strain Designation: K1227      Source of Strain: M. Russel
Sex: F- Chromosomal Markers: ompF627(T2R), tyrT5888(AS), oppC506::Tn10, fadL701(T2R), relA1, pitA10, spoT1, rrnB-2, mcrB1, creC510
Strain Comments:

• M.Russel, personal communication
• oppC506::Tn10-- cotransduces 83% with tyrT and 43% with trpA. It was shown to be within the oppC locus by Nichols et al. (1998).
• spoT1-- In addition to the 6bp insertion, there is a C to T transition resulting in an H257Y substitution.
• rrnB-2-- : loss of spacer loop sequence
• creC510-- The constitutive phenotype is due to an R77P amino acid substitution
• creC510 was formerly called phoM510
• oppC506::Tn10 was formerly called zci-506::Tn10
• = tetracycline resistant
• AS = amber(UAG) suppressor
• Const = constitutive
• T2R = T2 Resistant
