1. Second, blocks may be caused by a deficiency of enzyme co-factors - that is, various vitamin or trace element deficiencies.

2. The gene for membrane cofactor protein is the next target.

3. Magnesium is cofactor in hundreds of enzymatic reactions.

4. An enzyme without its cofactor is termed an apoenzyme.

5. They may have a nonprotein part (cofactor), which may be an inorganic ion or an organic constituent (coenzyme).

6. Apoenzyme An ENZYME whose cofactor or prosthetic group has been removed (e. g. via dialysis) rendering it catalytically inactive. It is the protein part of a conjugate enzyme.

7. Magnesium is involved as a cofactor in many enzyme transfers.

8. Cofactor (coenzyme) A nonprotein substance that helps an enzyme to carry out its activity.

9. Cofactor: An atom, organic molecule group that is necessary for the catalytic activity of many enzymes.

10. Folate cofactor for this enzyme, which is part of the pathway of homocysteine metabolism in cells.

11. One of the key steps in those reactions is that the distortion of corrin ring of the cofactor is induced by enzymes, and then the cobalt-carbon bond is broken to produce a '-deoxyadenosyl radical.

11.

12. P 53 may interact with other proteins as a activator, an repressor or cofactor.

13. The results show that the suitable selection of retention agent and its cofactor was very important.

14. This paper includes enzyme crosslinking, site - directed mutagenesis, small molecular compounds, homo - functionality polymerization, cofactor introduction.

15. Another result is presented a topological formula for any 2-order algebraic cofactor in passive network node admittance matrixes.

16. Many enzymes will not work without the presence of an additional nonprotein substance called a cofactor.

17. When a catalytically active enzyme forms a complex with a cofactor a holoenzyme is produced.

18. Snake venom LAOs are usually dimeric flavoprotein, which contain non-covalently bound FAD or FMN as cofactor.

19. Methylmalonic acidemia is an inherited metabolic disorder, which is caused by deficiency of methylmalonyl-coenzyme A mutase or its cofactor adenosylcobalamin.
