Organism

Escherichia coli (strain K12) [Reference proteome] [HAMAP]

Taxonomic identifier

83333 [NCBI]

Taxonomic lineage

cellular organisms › Bacteria › Proteobacteria › Gammaproteobacteria › Enterobacteriales › Enterobacteriaceae › Escherichia › Escherichia coli

Protein attributes

Sequence length	588 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Catalytic activity	Adenine + H2O = hypoxanthine + NH3. Ref.4 Ref.5
Cofactor	Manganese. Ref.4 Ref.5
Subunit structure	Homodimer. Ref.4
Induction	Repressed by H-NS. Activated by insertion of a variety of IS elements into a region extending from -145 to +13 relative to the transcription start site. IS elements essentially eliminate the H-NS-mediated silencing, but also stimulate ade expression 2-3 fold independently of the H-NS protein. Ref.5
Miscellaneous	Ade is a cryptic gene in wild-type strains. The physiological conditions that lead to its activation are unknown. HAMAP-Rule MF_01518
Sequence similarities	Belongs to the adenine deaminase family.
Biophysicochemical properties	pH dependence: Optimum pH is 6.5-7.0. HAMAP-Rule MF_01518 Temperature dependence: Optimum temperature is 60 degrees Celsius.
