Depositor Comments

MG1655-C321 -- All 321 UAG codons changed to UAA.
mutS+ -- Restores normal spontaneous mutation frequency.
(λ-) – Deleted Lambda Phage operon to allow growth at 37C.
Δ(ybhB-bioAB)::zeoR – Deletion of biotin biosynthetic operon using Zeocin cassette; strain is d-biotin auxotroph.
ΔprfA – Deletion of polypeptide release factor 1 (RF1) to prevent translation termination at UAG codons.
ΔserB – Deletion of phosphoserine phosphatase to provide intracellular source of phosphoserine; strain is Serine auxotroph.
The genome sequence of a similar strain (C321.deltaA) was deposited at NCBI (accession # CP006698.1)
