The Biochemical Journal
|September 1, 1978
Summary
This study shows deoxycytidine kinase from animal tissues can be purified using Cibacron Blue affinity chromatography. Adenosine triphosphate (ATP) selectively elutes the enzyme, enabling efficient, reusable purification.
Area of Science:
- Biochemistry
- Enzymology
- Protein Purification
Background:
- Deoxycytidine kinase is a crucial enzyme in nucleotide metabolism.
- Efficient purification methods are essential for studying enzyme kinetics and function.
Purpose of the Study:
- To develop a rapid and effective method for purifying deoxycytidine kinase.
- To investigate the use of affinity chromatography for enzyme isolation.
Main Methods:
- Affinity chromatography using Cibacron Blue 3G-A coupled to Sepharose CL-6B.
- Selective elution of the enzyme using adenosine triphosphate (ATP).
Main Results:
- Deoxycytidine kinase from various animal tissues binds effectively to the Cibacron Blue adsorbent.
- Single-step purification yielded 17-89-fold enrichment of the enzyme.
- The affinity adsorbent demonstrated reusability.
Conclusions:
- Cibacron Blue affinity chromatography is a highly efficient method for deoxycytidine kinase purification.
- ATP-mediated elution provides a selective and effective means of enzyme recovery.
- This method offers a valuable tool for biochemical and enzymatic studies.
