Notes
This strain carries the H12 amber mutation (TAG) in the phosphatase gene.
This strain carries the supF suppressor (inserts tyrosine at the amber position) and is therefore capable of suppressing the H12 phosphatase nonsense mutation, as well as amber mutations in other genes. However, the efficiency of suppression may vary considerably depending on the sequence context of the amber codon.
