Sphingomyelin synthesis in Ascaridia galli

I Bankov1, J Barrett

  • 1Institute of Parasitology, Bulgarian Academy of Sciences, Sofia.

International Journal for Parasitology
|December 1, 1993
PubMed
Summary

Adult Ascaridia galli, a type of roundworm, utilize [U-14C] serine to synthesize sphingomyelin. This indicates the presence of key enzymes essential for sphingomyelin biosynthesis in these parasites.

Area of Science:

  • Parasitology
  • Biochemistry
  • Molecular Biology

Background:

  • Sphingomyelin is a vital component of cell membranes.
  • Understanding its synthesis in parasites like Ascaridia galli is crucial for potential drug targets.

Purpose of the Study:

  • To investigate the metabolic pathway of sphingomyelin synthesis in adult Ascaridia galli.
  • To identify the enzymes involved in this pathway.

Main Methods:

  • Adult Ascaridia galli were incubated with radiolabeled [U-14C] serine.
  • Incorporation of the label into sphingomyelin intermediates was analyzed.

Main Results:

  • [U-14C] serine was incorporated into ketosphinganine, sphinganine, sphingosine, ceramide, and sphingomyelin.
  • Evidence supports the presence of all five key enzymes in the sphingomyelin synthesis pathway.

Conclusions:

  • Ascaridia galli possesses the complete enzymatic machinery for sphingomyelin synthesis.
  • This pathway represents a potential target for antiparasitic interventions.
