CGSC Strain#: 1932
Strain Designation: AB1932      Source of Strain: G. Eggertsson
Other Designations: X7185
Sex: F- Chromosomal Markers: lacY1 or lacZ4, tsx-6, glnX44(AS), galK2(Oc), xyl-7 or xylA5, ΔargH1, thiE1, metA28
Strain Comments:

• 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.
• 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
