Insights into Aldehyde Dehydrogenase Enzymes: A Structural Perspective.

Area of Science:

• Biochemistry
• Molecular Biology
• Enzymology

Background:

• Aldehyde dehydrogenases (ALDHs) are crucial enzymes involved in various cellular processes, including detoxification and biosynthesis.
• Dysfunctional ALDHs can lead to the accumulation of cytotoxic substrates, contributing to severe diseases such as cancer and neurological disorders.

Purpose of the Study:

• To elucidate the structure-function relationship of aldehyde dehydrogenases (ALDHs).
• To provide a global understanding of ALDH structure, function, and their role in disease.
• To bridge the knowledge gap between human and prokaryotic ALDHs.

Main Methods:

• Review and synthesis of structural, functional, and biophysical studies on bacterial and eukaryotic ALDHs.
• Analysis of key structural features: cofactor binding domain, active site, and oligomerization mechanism.

Main Results:

• Identified principal structural features critical for ALDH activity: cofactor binding domain, active site, and oligomerization.
• Highlighted the diversity within the ALDH superfamily through comparative studies.

Conclusions:

• A comprehensive understanding of ALDH structure-function relationships is essential for comprehending ALDH-associated diseases.
• Comparative analysis of diverse ALDHs offers insights into conserved mechanisms and disease relevance.
