Ak1, also known as Adenylate kinase isoenzyme 1 isoform 1, is an enzyme involved in regulating the adenine nucleotide composition within a cell by catalyzing the reversible transfer of the terminal phosphate group between ATP and AMP. This protein is found in the cytosol of skeletal muscle, brain and erythrocytes.It is a small ubiquitous enzyme which is essential for maintenance and cell growth. Defects in Ak1 are the cause of a form of hemolytic anemia. Recombinant mouse Ak1 protein, fused to His-tag at N-terminus, was expressed in E.coli and purified by using conventional chromatography techniques.
