Mutation Location Certainty Display tsx-467(Am) 0.00 1 tsx-467(Am) araA230 1.44 1 araA230 lon- 9.90 1 lon- rpsL227(strR) 74.84 1 rpsL227(strR) hsdR- 99.00 1 hsdR- mal+([K-12])(LamS) 1000.00 1 [mal+]K-12(λS) - Comments:
- Not a K-12 strain. This is an E. coli B derivative.
- This is not a descendant of E. coli Bc251 as originally thought. See Daegelen et al. reference for derivation. The malB region was transduced in from E. coli K-12 strain W3110.
- This strain has been evolved for 2000 generations in Glucose minimal medium
