Moonlighting enzymes in parasitic protozoa

Area of Science:

• Biochemistry
• Molecular Biology
• Parasitology

Background:

• Enzymes exhibit moonlighting by performing non-enzymatic functions in diverse cellular processes.
• Moonlighting enzymes are found in both prokaryotes and eukaryotes, with discoveries often being unexpected.
• The multi-functionality of enzymes necessitates caution when interpreting phenotypes from gene deletion or silencing.

Purpose of the Study:

• To provide an overview of enzyme moonlighting in parasitic protists.
• To discuss unequivocal and putative examples of moonlighting in these organisms.
• To explore how parasite biology might influence the occurrence or evolution of moonlighting.

Main Methods:

• Literature review of moonlighting enzymes in parasitic protists.
• Analysis of known and potential non-enzymatic roles of enzymes.
• Discussion of evolutionary and biological factors influencing enzyme moonlighting.

Main Results:

• Several examples of moonlighting enzymes in parasitic protists are presented.
• The study highlights the potential for widespread, yet often unrecognized, non-enzymatic functions.
• Factors such as parasite-specific biology may shape the landscape of enzyme moonlighting.

Conclusions:

• Enzyme moonlighting is a significant biological phenomenon in parasitic protists.
• Understanding these non-enzymatic roles is crucial for interpreting experimental results and parasite biology.
• Further research is needed to fully elucidate the extent and implications of moonlighting in parasites.
