The E-NTPDase family of ectonucleotidases: Structure function relationships and pathophysiological significance
Ectonucleotidases are ectoenzymes that hydrolyze extracellular nucleotides to the respective nucleosides. Within the past decade, ectonucleotidases belonging to several enzyme families have beenExpand

Cellular function and molecular structure of ecto-nucleotidases
Ecto-nucleotidases play a pivotal role in purinergic signal transmission. They hydrolyze extracellular nucleotides and thus can control their availability at purinergic P2 receptors. They generateExpand

Purinergic signalling in the nervous system: an overview
Purinergic receptors, represented by several families, are arguably the most abundant receptors in living organisms and appeared early in evolution. After slow acceptance, purinergic signalling inExpand

Ectonucleotidases: Some recent developments and a note on nomenclature
Extracellular nucleotides such as ATP, ADP, UTP, UDP, and also diadenosine polyphosphates act as signaling molecules and can be inactivated by hydrolysis via ectonucleotidases. A considerable numberExpand

  • 15 July 1992
5'-Nucleotidase activity was first described in heart and skeletal muscle about 60 years ago (Reis, 1934). It catalyses the hydrolysis of phosphate esterified at carbon 5' of the ribose andExpand

Signalling via ATP in the nervous system
Strong evidence has been provided that ATP can act as a transmitter not only in smooth muscle but also in peripheral ganglia and in brain. The cloning and molecular identification of two putative ATPExpand

Distribution of ectonucleotidases in the rodent brain revisited
Nucleotides comprise a major class of signaling molecules in the nervous system. They can be released from nerve cells, glial cells, and vascular cells where they exert their function via ionotropicExpand
