NATs at a glance

Area of Science:

• Biochemistry
• Molecular Biology
• Human Physiology

Background:

• Most proteins undergo N-terminal acetylation co-translationally via N-terminal acetyltransferases (NATs).
• This modification influences protein functionality and cellular processes.
• Defects in N-terminal acetylation are linked to various human diseases.

Purpose of the Study:

• To provide an overview of human N-terminal acetyltransferase (NAT) enzymes.
• To describe NAT properties, substrate specificity, and cellular functions.
• To explore the connections between NATs and human pathology.

Main Methods:

• Literature review of N-terminal acetylation.
• Analysis of N-terminal acetyltransferase (NAT) enzyme properties.
• Examination of genetic studies linking N-terminal acetylation to disease.

Main Results:

• Human NAT enzymes exhibit diverse properties and substrate specificities.
• N-terminal acetylation plays essential roles in fundamental cellular processes.
• Dysregulation of N-terminal acetylation is implicated in human diseases.

Conclusions:

• N-terminal acetylation is a vital post-translational modification with significant physiological and pathological implications.
• Understanding human NAT enzymes is crucial for deciphering their roles in health and disease.
