Definition of the noun Atpase

What does Atpase mean as a name of something?

noun - plural: ATPases

  1. [biochemistry] A type of enzyme which works to convert adenosine triphosphate (ATP) into adenosine diphosphate (ADP) and a free phosphate ion, thereby releasing energy to be used in cellular activity.


  1. ATPase: ATPases are a class of enzymes that catalyze the decomposition of ATP into ADP and a free phosphate ion. This dephosphorylation reaction releases energy, which the enzyme harnesses to drive other chemical reactions that would not otherwise occur. This process is widely used in all known forms of life.
    • also known as Adenozynotrifosfataza
  2. Atpase a.k.a. dynein, axonemal, heavy chain 8 is a gene.
    • also known as dynein, axonemal, heavy polypeptide 8; OTTHUMP00000039711
