Summary
Terpenoid complexity arises from poly-isoprenyl precursors via carbocationic mechanisms. While enzyme structures reveal insights into simpler reactions, complex cyclizations and rearrangements in terpenoid biosynthesis require further investigation.
Area of Science:
- Biochemistry
- Natural Product Chemistry
- Enzymology
Background:
- Terpenoid natural products exhibit significant structural complexity.
- Their common origin from (poly)isoprenyl precursors is well-established.
- Complexity arises from variable cyclization and rearrangement of hydrocarbon skeletons.
Purpose of the Study:
- To explore the enzymatic mechanisms underlying terpenoid backbone formation.
- To highlight the limitations in understanding complex cyclization and rearrangement reactions.
- To discuss potential future research directions.
Main Methods:
- Analysis of high-resolution crystal structures of enzymes involved in terpenoid biosynthesis.
- Review of established knowledge on terpenoid backbone assembly and diversification.
- Case studies illustrating current understanding and limitations.
Main Results:
- Terpenoid backbone assembly and diversification share a common carbocationic mechanism.
- Enzymatic insights are available for elongation and simpler cyclizations.
- Understanding of complex cyclization and rearrangement mechanisms remains limited.
Conclusions:
- Further research is needed to elucidate the mechanisms of complex terpenoid cyclizations and rearrangements.
- Structure-function relationships of enzymes involved in these complex reactions are not fully understood.
- Bridging the knowledge gap in complex terpenoid biosynthesis is crucial.

01:18ATP Synthase: Structure
ATP synthase or ATPase is among the most conserved proteins found in bacteria, mammals, and plants. This enzyme can catalyze a forward reaction in response to the electrochemical gradient, producing ATP from ADP and inorganic phosphate. ATP synthase can also work in a reverse direction by hydrolyzing ATP and generating an electrochemical gradient. Different forms of ATP synthases have evolved special features to meet the specific demands of the cell. Based on their specific feature, ATP...
01:48ATP Synthase: Mechanism
In animals, the mitochondrial F1F0 ATP synthase is the key protein that synthesizes ATP molecules through a complex catalytic mechanism. While the nuclear genome encodes the majority of ATP synthase subunits, the mitochondrial genome encodes some of the enzyme's most critical components. The formation of this multi-subunit enzyme is a complex multi-step process regulated at the level of transcription, translation, and assembly. Defects in one or more of these steps can result in decreased ATP...
01:13Introduction to Mechanisms of Enzyme Catalysis
For many years, scientists thought that enzyme-substrate binding took place in a simple "lock-and-key" fashion. This model stated that the enzyme and substrate fit together perfectly in one instantaneous step. However, current research supports a more refined view scientists call induced fit. The induced-fit model expands upon the lock-and-key model by describing a more dynamic interaction between enzyme and substrate. As the enzyme and substrate come together, their interaction causes a mild...

01:41The Supercomplexes in the Crista Membrane
The mitochondrial cristae membrane is the primary site for the oxidative phosphorylation (OXPHOS) process of energy conversion mediated through respiratory complexes I to V. These complexes have been widely studied for decades, and it has been proven that they form supramolecular structures called respiratory supercomplexes (SC). These higher-order complexes may be crucial in maintaining the biochemical structure and improving the physiological activity of the individual complexes while...
01:07Catalytically Perfect Enzymes
The theory of catalytically perfect enzymes was first proposed by W.J. Albery and J. R. Knowles in 1976. These enzymes catalyze biochemical reactions at high-speed. Their catalytic efficiency values range from 108-109 M-1s-1. These enzymes are also called 'diffusion-controlled' as the only rate-limiting step in the catalysis is that of the substrate diffusion into the active site. Examples include triose phosphate isomerase, fumarase, and superoxide dismutase.
