Strain Comments:

• phoA4(Am)-- is Garen's phoAS26 . It is suppressed by leuX151, glnV33(=supE33) and serU132(=supD32).
• spoT1-- In addition to the 6bp insertion, there is a C to T transition resulting in an H257Y substitution.
• serU132(AS) was formerly called Su1⁺
• serU132(AS) was formerly called supD32
• Am = amber(UAG) mutation
• AS = amber(UAG) suppressor
