Depositor Comments

E. coli MG1655 Delta(ybhB-bioAB)::zeoR Delta prfA; all 321 UAG codons changed to UAA

This strain is mutS+, which causes a normal spontaneous mutation frequency of ~1E-10. This strain is auxotrophic for d-biotin.

The genome sequence of a similar strain (C321.deltaA) was deposited at NCBI (accession # CP006698.1).
