Lactoferrin (LF) is an iron-binding glycoprotein found predominantly in milk and in granulocytes. LF is extremely polyfunctional protein some biological functions of which are determined by its capacity to bind iron, but many other functions are iron-independent. In this article we show for the first time that LF interacts with a number of various mononucleotides.
