CGSC Strain#: 6200
Strain Designation: KL692      Source of Strain: M.C. Cappello
Sex: F- Chromosomal Markers: secA209(aziR), Δ(gpt-lac)5, λ^-, trpA9605(Am), his-85(Am), gyrA19(NalR), rpsL171(strR), metE90, trpR55
Strain Comments:

• Δ(gpt-lac)5-- is the deletion Δ( pro-lac)_X111 of Jacob and originated in the strain Hfr 3000 X111.
• trpA9605(Am)-- is an amber mutation. It is suppressed by supD32.
• his-85(Am)-- is an amber mutation. It is suppressed by supD32.
• metE90-- is probably metE70.
• trpR55-- is trpR2 of Yanofsky. It is a frameshift mutation. Trp levels are indistinguishable from those in trpR deletions or amber mutations (no functional repressor).
• his-85(Am) was formerly called his-29
• secA209(aziR) was formerly called azi-9
• Am = amber(UAG) mutation
• aziR = azide resistance
• NalR = Nalidix.acidResist.
• strR = streptomycin resist.
