Strain Designation: DR1984      Source of Strain: A. Sancar
Sex: F- Chromosomal Markers: thr-1, araC14, leuB6(Am), Δ(gpt-proA)62, lacY1, tsx-33, galK2(Oc), λ^-, Rac-0, uvrC34, hisG4(Oc), rfbC1, recA1, rpsL31(strR), kdgK51, xylA5, mtl-1, argE3(Oc), thiE1
Strain Comments:

• leuB6(Am)-- Suppressed by serU suppressor (supH)
• galK2(Oc)-- is a GAA(glu) to TAA(ochre) mutation, residue 134. Oller et al.1993. Apparently non-suppressible, since all revertants found were at the ochre site.
• recA1-- : Missense mutation, altered isoelectric point. Sequenced: G to A for Nuc. 720 (Gly 160 Asp).
• Δ(gpt-proA)62 was formerly called proA2
• galK2(Oc) was formerly called gal₂
• rfbC1 was formerly called rfbD1
• thiE1 was formerly called thi-1
• Am = amber(UAG) mutation
• Oc = ochre(UAA) mutation
• strR = streptomycin resist.
