Sex: Hfr    Point of Origin#: 2A   Map Position: 12.20   Direction of Marker Transfer: Counterclockwise
Chromosomal Markers: garB10, fhuA22, phoA4(Am), tolQ7(Am), zbg-2225::Tn10, ompF627(T2R), fadL701(T2R), relA1, pitA10, spoT1, rrnB-2, mcrB1, creC510
Strain Comments:

• phoA4(Am)-- is Garen's phoAS26 . It is suppressed by leuX151, glnV33(=supE33) and serU132(=supD32).
• 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
• tolQ7(Am) was formerly called fii-1
• Am = amber(UAG) mutation
• Const = constitutive
• T2R = T2 Resistant
