Strain Designation: DF262      Source of Strain: D. Fraenkel
Sex: Hfr    Point of Origin#: 2A   Map Position: 12.20   Direction of Marker Transfer: Counterclockwise
Chromosomal Markers: fhuA22, ompF627(T2R), fadL701(T2R), eno-3, relA1, pitA10, spoT1, rrnB-2, mcrB1, creC510
Strain Comments:

• 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
• Const = constitutive
• T2R = T2 Resistant
