adenylate kinase

adenylate kinase /aden·yl·ate ki·nase/ (ki´nās) an enzyme that catalyzes the conversion of two molecules of ADP to AMP and ATP; it occurs predominantly in muscle, providing energy for muscle contraction.

adenylate kinase

n.

An enzyme that catalyzes the phosphorylation of one molecule of ADP by another, yielding ATP and AMP.

---

adenylate kinase,

an enzyme in skeletal muscle that makes possible the reaction ATP + AMP = 2ADP. Also called myokinase.

---

adenylate

a salt, anion or ester of adenylic acid.

---

adenylate cyclase

an enzyme that catalyzes the conversion of adenosine triphosphate (ATP) to cyclic adenosine monophosphate (cAMP) and inorganic pyrophosphate. It is activated by the attachment of a hormone or neurotransmitter to a specific membrane-bound receptor.

adenylate kinase

enzyme catalyzing the conversion of two moles of ADP to ATP and AMP, thereby equilibrating ADP with ATP and AMP. Controls the adenylate energy charge of a cell, particularly muscle cells. Called also myokinase.
