Figure 1-1: A flow chart of the two types of cofactors. Apoenzyme-An enzyme that requires a cofactor but does not have one bound. An apoenzyme is an inactive enzyme, activation of the enzyme occurs upon binding of an organic or inorganic cofactor. Holoenzyme-An apoenzyme together with its cofactor. A holoenzyme is complete and catalytically active. Most cofactors are not covalently bound but instead are tightly bound. However, organic prosthetic groups such as an iron ion or a vitamin can be covalently bound.
A ribozyme (ribo nucleic acid en zyme) is an RNA molecule that can help certain biochemical reactions.similar to the action of protein enzymes. Also called catalytic RNA, ribozymes work in the ribosome to link amino acids during protein synthesis.mproved variants of the Round-18 polymerase ribozyme have been developed. B6.61 is able to add up to 20 nucleotides to a primer template in 24 hours, until it decomposes by cleavage of its phosphodiester bonds. The tC19Z ribozyme can add up to 95 nucleotides with great accuracy.
