Zinc biochemistry in normal and neoplastic growth processes

Area of Science:

• Biochemistry
• Molecular Biology
• Enzymology

Background:

• Zinc is an essential trace element crucial for organismal growth.
• Zinc deficiency leads to growth arrest, indicating critical metabolic roles.
• Over 80 enzymes utilize zinc as a coenzyme.

Purpose of the Study:

• To highlight the essential role of zinc in biological systems.
• To emphasize zinc's involvement in nucleic acid metabolism.
• To identify zinc-dependent enzymes, including reverse transcriptases linked to leukemia.

Main Methods:

• Literature review of zinc's biochemical functions.
• Analysis of zinc metalloenzymes.
• Examination of zinc's role in nucleic acid metabolism.

Main Results:

• Zinc deficiency causes growth arrest in various species.
• Zinc acts as a coenzyme for more than 80 enzymes.
• Reverse transcriptases, implicated in leukemia, are zinc-dependent enzymes.

Conclusions:

• Zinc is indispensable for growth and metabolism across species.
• Zinc's function as a coenzyme is critical for numerous enzymatic processes.
• Further research into zinc's role in nucleic acid metabolism and diseases like leukemia is warranted.
