Holoenzyme is a catalytically active enzyme that consists of apoenzyme and cofactor. Cofactors can make reactions that cannot be done by standard twenty amino acids. Cofactors are divided in two groups:
Use of the same coenzyme usually means that enzymes catalyse similar mechanisms [1].
Sigma 70 and RNA Polymerase II[2] is an example of a holoenzyme used in transcription of prokaryotes.
