Protein Prenyltransferases and Their Inhibitors: Structural and Functional Characterization

Area of Science:

• Biochemistry
• Molecular Biology
• Drug Discovery

Background:

• Protein prenylation is a vital post-translational modification.
• It regulates small GTPases, including the Ras superfamily, affecting localization and activity.
• This process involves attaching farnesyl or geranylgeranyl groups catalyzed by four prenyltransferases.

Purpose of the Study:

• To review the structures of four prenyltransferases: FTase, GGTase-I, GGTase-II, and GGTase-III.
• To summarize the current research status on inhibitors of these prenyltransferases.
• To highlight the therapeutic potential of prenyltransferase inhibitors in various diseases.

Main Methods:

• Literature review of prenyltransferase structures.
• Summary of research on prenyltransferase inhibitors.
• Analysis of therapeutic benefits in disease models.

Main Results:

• Detailed structural overview of FTase, GGTase-I, GGTase-II, and GGTase-III provided.
• Current research on inhibitors for each prenyltransferase is summarized.
• Evidence for therapeutic benefits of prenyltransferase inhibitors in cancer, neurological disorders, and infections is presented.

Conclusions:

• Prenyltransferase inhibitors represent a promising therapeutic strategy.
• Targeting protein prenylation offers a pathway for treating diverse diseases.
• Further research into prenyltransferase structures and inhibitors is warranted.
