CGSC Strain#: 2568
Strain Designation: GE130      Source of Strain: G. Eggertsson
Sex: F- Chromosomal Markers: Δ(gpt-proA)62, lacY1, tsx-29, glnX44(AS), galK2(Oc), hisG4(Oc), xylA5, mtl-1, thiE1, purD38::Mu
Strain Comments:

• transduction: argA3 -> argA⁺ proA2 = DE62.
• glnX44(AS)-- Mutation is a C to T transition at nucleotide 34 (3rd position of the anticodon)
• 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.
• Δ(gpt-proA)62 was formerly called proA2
• galK2(Oc) was formerly called gal₂
• glnX44(AS) was formerly called su⁺_II
• glnX44(AS) was formerly called supE44
• glnX44(AS) was formerly called glnV44
• thiE1 was formerly called thi-1
• AS = amber(UAG) suppressor
• Oc = ochre(UAA) mutation
