Taxonomic identifier

1423 [NCBI]

Taxonomic lineage

Bacteria › Firmicutes › Bacillales › Bacillaceae › Bacillus

Protein attributes

Sequence length	217 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Catalyzes the reversible transfer of the terminal phosphate group between ATP and AMP. This small ubiquitous enzyme involved in the energy metabolism and nucleotide synthesis, is essential for maintenance and cell growth. This small ubiquitous enzyme is essential for maintenance and cell growth.
Catalytic activity	ATP + AMP = 2 ADP.
Pathway	Purine metabolism; AMP biosynthesis via salvage pathway; AMP from ADP: step 1/1.
Subunit structure	Monomer.
Subcellular location	Cytoplasm.
Induction	By superoxide.
Domain	Consists of three domains, a large central CORE domain and two small peripheral domains, AMP binding and LID. The LID domain closes over the site of phosphoryl transfer upon ATP binding.
Miscellaneous	The zinc ion does not participate in catalysis. It has a structural role in stabilizing the LID domain, which does not seem to be involved in directly binding DNA/RNA By similarity.
Sequence similarities	Belongs to the adenylate kinase family.
Biophysicochemical properties	Temperature dependence: Optimum temperature is 45 degrees Celsius. Thermal denaturation midpoint (Tm) is 47.6 degrees Celsius and is raised to 66.0 degrees Celsius when AK is complexed with the inhibitor Ap5A.
