一般描述
Native, yeast myokinase. Myokinase reversibly transfers phosphate from ATP to AMP, thus forming two molecules of ADP. The enzyme is specific for adenine nucleotides and catalyzes the reaction only in the presence of a divalent metal ion (e.g. Mg2+, Ca2+, Co2+, Mn2+, or Ni2+).
Note: 1 KU = 1000 units.
外形
Lyophilized from potassium phosphate buffer.
制备说明
Following reconstitution, aliquot and freeze (-20°C). Stock solutions are stable for up to 6 months at -20°C.

The complete amino acid sequence of cytosolic adenylate kinase (MgATP + AMP----MgADP + ADP) from baker's yeast has been determined. Tryptic and clostripaic cleavage of the protein yielded 27 and 10 fragments, respectively. They were sequenced with either a solid-phase

Yeast adenylate kinase (Aky2p, Adk1p) occurs simultaneously in cytoplasm and mitochondrial intermembrane space. It has no cleavable mitochondrial targeting sequence, and the signal for mitochondrial import and submitochondrial sorting is largely unknown. The extreme N terminus of Aky2p is able

Thiamine triphosphate (ThTP) is found at low concentrations in most animal tissues and it may act as a phosphate donor for the phosphorylation of proteins, suggesting a potential role in cell signaling. Two mechanisms have been proposed for the enzymatic

The structural gene for yeast adenylate kinase (AKY) has been isolated and analyzed with respect to its nucleotide sequence. Southern and northern analyses imply that the gene is single copy and is transcribed into an mRNA of about 1,100 bases.

An improved homogeneous preparation of adenylate kinase (ATP:AMP phosphotransferase, ATP + AMP in equilibrium 2 ADP) from baker's yeast was attained by extraction using ethyl acetate and successive column chromatography on Affi-Gel blue, Sephadex G-100, phosphocellulose and Sephacryl S-200. The
