Notes

[back to top]


E. coli IaaA is cleaved before Thr179 to expose an N-terminal nucleophile and to produce two subunits.[4] CysB regulon, sensitive to cysteine repression. The start of the Salmonella IaaA is confirmed by N-terminal sequencing of the IaaA precursor. Salmonella IaaA has been shown to have isoaspartyl-tripeptidase activity.[6] E. coli probably also has tripeptidase activity.[5] iaaA is a non-essential gene.[5]
