CGSC Strain#: 1035
Strain Designation: AB1035      Source of Strain: E.A. Adelberg
Sex: F' Episome/Plasmid: F14-21
   Plasmid Markers/Mutations: ilvP-271
Chromosomal Markers: lacY1 or lacZ4, tsx-6, galK2(Oc), xylA5, ilvC7, argE3(Oc), thiE1, tfr-3
Strain Comments:

• 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
• thiE1 was formerly called thi-1
• Oc = ochre(UAA) mutation
