Strain Designation: CS8 Asp/23      Source of Strain: Marcus & Halpern
Sex: Hfr    Point of Origin#: 2A   Map Position: 12.20   Direction of Marker Transfer: Counterclockwise
Chromosomal Markers: garB10, fhuA22, ompF627(T2R), fadL701(T2R), relA1, gltSo8(ts), spoT1, metB1, aspA23, mcrB9999, creC510
Strain Comments:

• spoT1-- In addition to the 6bp insertion, there is a C to T transition resulting in an H257Y substitution.
• creC510-- The constitutive phenotype is due to an R77P amino acid substitution
• creC510 was formerly called phoM510
• Const = constitutive
• T2R = T2 Resistant
• ts = Temperature Sensitive
