macroenzyme

noun ! Definition from Wiktionary (CC BY-SA). More about macroenzyme at Wordnik → Where our words come from →

1. An enzyme of macromolecular size due to unusual biopolymerization or immune complexing, such as when a normal enzyme is protein-bound, typically by immunoglobulins (antibodies); macroenzymes by themselves are not always pathophysiologic or pathogenic, but their occurrence is increased in certain diseases (their formation is encouraged by some pathogenetic processes).
