CGSC Strain#: 5746
Strain Designation: JM96      Source of Strain: M.C. Jones-Mortimer
Sex: F- Chromosomal Markers: thr-1, leuB6(Am), fhuA2, lacY1, glnV44(AS), gal-6, λ^-, trp-1, hisG1(Fs), rfbC1, cysH56, galP63, Δ(gltB-gltF)500, malT1(λ^R), xyl-7, mtlA2, ΔargH1, rplL9(L?), thiE1
Strain Comments:

• leuB6(Am)-- Suppressed by serU suppressor (supH)
• Δ(gltB-gltF)500-- :Glt^- phenotype in gltB mutant requires presence of a gdhA mutation as well. 0.2% aspartate is a better N-source than glutamate because of uptake(Pahel et al).
• Δ(gltB-gltF)500 was formerly called gltB31
• Δ(gltB-gltF)500 was formerly called aspB21
• Δ(gltB-gltF)500 was formerly called aspB24
• glnV44(AS) was formerly called supE44
• glnV44(AS) was formerly called su⁺_II
• rfbC1 was formerly called rfbD1
• thiE1 was formerly called thi-1
• xyl-7 was formerly called xylA7
• Am = amber(UAG) mutation
• AS = amber(UAG) suppressor
• Fs = Frameshift mutation
• L? = assignment uncertain
• LamR = Lambda-resistant
