CGSC Strain#: 5833
Strain Designation: NH5050      Source of Strain: P. Howard-Flanders
Sex: F- Chromosomal Markers: lac-61, glnX44(AS), gal-44, λ^-, sbcB15, recA1, recB21, endA1, thiE1, deo-27 or deo-43
Strain Comments:

• This strain is φX-sensitive but plates φX poorly with turbid plaques. This is an E. coli K-12 C hybrid.
• glnX44(AS)-- Mutation is a C to T transition at nucleotide 34 (3rd position of the anticodon)
• recA1-- : Missense mutation, altered isoelectric point. Sequenced: G to A for Nuc. 720 (Gly 160 Asp).
• endA1-- G to A transition mutation resulting in E208K amino acid substitution.
• 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
• = good miniprep dsDNA quality
• AS = amber(UAG) suppressor
