UniProtKB - P19219 (ADAA_BACSU)
Protein
Bifunctional transcriptional activator/DNA repair enzyme AdaA
Gene
adaA
Organism
Bacillus subtilis (strain 168)
Status
Functioni
Is involved in the adaptive response to alkylation damage in DNA caused by alkylating agents. Repairs the methylphosphotriester lesions in DNA by a direct and irreversible transfer of the methyl group to one of its own cysteine residues.
The methylation of AdaA by methylphosphotriesters in DNA leads to its activation as a transcriptional regulator that activates the transcription of the ada operon which consists of adaA and adaB, and of the adjacent gene alkA.
Catalytic activityi
- a methylphosphotriester deoxyribonucleoside in DNA + L-cysteinyl-[protein] = a deoxyribonucleotide in DNA + H+ + S-methyl-L-cysteinyl-[protein]1 PublicationEC:2.1.1.n111 Publication
