Biological Chemistry of Organelle Formation

Eukaryotic cells comprise a plurality of organelles unique by way of their particular membranes and contents. Their biogenesis happens via development and department of preexisting buildings instead of de novo. Mitochondria and chloroplasts, which seem to be descended from prokaryotic ancestors, have retained a few DNA and the biosynthetic power for its expression.

In Tabernaemontana divaricata treatment of plant cell suspension cultures with an elicitor cause inhibition of CS activity [24, 25]. This response is accompanied by stimulation of activity of constitutive enzyme activities of the isoprenoid pathway leading to 2,3-oxidosqualene (squalene synthase and squalene oxidase), and induction of enzymes required for biosynthesis of pentacyclic triterpenoid phytoalexins (bAS and aAS). Thus inhibition of the branchpoint enzyme CS results in increased flux through the triterpenoid pathway.
