Strain Designation: KL211      Source of Strain: M.C. Cappello
Sex: Hfr    Point of Origin#: 12   Map Position: 68.80   Direction of Marker Transfer: Clockwise
Chromosomal Markers: fhuA2::IS2, lacY1, tsx-1, glnX44(AS), gal-6, λ^-, purF1, argG34, argG35, xyl-7, mtlA2, metB1
Strain Comments:

• There may be a second arg in this strain ( arg-35). Some recombinants are arg⁺, some are argG^- and some are arg^-, but not argG^-.
• glnX44(AS)-- Mutation is a C to T transition at nucleotide 34 (3rd position of the anticodon)
• purF1-- is a very stable mutation and may be an intragenic deletion.
• fhuA2::IS2 was formerly called fhuA2
• glnX44(AS) was formerly called su⁺_II
• glnX44(AS) was formerly called supE44
• glnX44(AS) was formerly called glnV44
• xyl-7 was formerly called xylA7
• ::IS2 = Insertion of IS2
• AS = amber(UAG) suppressor
