title: The possible role of ATP-dependent proteolysis on the solubilization of methemoglobin reductase during reticulocyte maturation.
abstract: The ATP-dependent proteolytic system present in reticulocytes can release the active hydrophilic domain of cytochrome b5 and NADH-cytochrome b5 reductase from the endoplasmic reticulum, that in mature erythrocytes act as methemoglobin reductase.
