Apoprotein

Als Apoprotein (gr.: apo - von , prōton - das erste) bezeichnet man denjenigen Teil eines Proteins, welcher nur aus Aminosäuren besteht. Wenn noch die Prosthetische Gruppe dazukommt, erhält man ein vollständiges Protein (gr. holos = ganz; Holoprotein). Bei einem zusammengesetzten Enzym ist das Apoprotein identisch mit dem Apoenzym.
