Notes

[back to top]


AsnA and AsnB are redundant; an asparagine auxotrophy requires that both genes be mutated. AsnA uses ammonia as the nitrogen source. Residues 199-203 of zwf encode a NNWDN peptide involved in ChpA(MazF) toxicity that is likely converted to NNWNN by AsnA since an asnA deletion prevents NNWNN activity (Kolodkin-Gal, 2007).[4]
