Summary
Cyclic adenosine monophosphate (cAMP) signaling is now confirmed in plants. Researchers identified active adenylate cyclases (ACs) in plants, revealing their crucial roles in cellular regulation and physiological functions.
Area of Science:
- Plant molecular biology
- Biochemistry
- Cell signaling
Background:
- 3'-5'-cyclic adenosine monophosphate (cAMP) and adenylate cyclases (ACs) are key signaling molecules in bacteria, fungi, and animals.
- The presence and role of cAMP in plants have been controversial due to low concentrations and elusive enzymes.
- Previous studies showed plant responses to exogenous cAMP, but ACs remained unidentified.
Purpose of the Study:
- To identify and characterize adenylate cyclases (ACs) in higher plants.
- To elucidate the molecular mechanisms of cAMP synthesis and signaling in plants.
- To understand the biological roles of plant ACs in cellular and physiological functions.
Main Methods:
- Bioinformatic searches using conserved amino acid motifs from known ACs.
- In vitro enzymatic assays to confirm AC activity.
- In vivo studies to validate AC function in plant systems.
Main Results:
- Candidate proteins with adenylate cyclase activity were identified in higher plants.
- Active ACs were found to be part of multifunctional proteins, acting as molecular tuners.
- The discovery suggests numerous undiscovered ACs within plant proteomes with diverse functions.
Conclusions:
- Adenylate cyclases (ACs) are confirmed as functional components in higher plants.
- These ACs play significant roles in regulating cellular and physiological processes.
- Further research is expected to uncover more plant ACs and their widespread impact on plant mechanisms.

5.7K
Some GPCRs transmit signals through adenylyl cyclase (AC), a transmembrane enzyme. AC helps synthesize second messenger cyclic adenosine monophosphate (cAMP). AC catalyzes cyclization reaction and converts ATP to cAMP by releasing a pyrophosphate. The pyrophosphate is further hydrolyzed to phosphate by the enzyme pyrophosphatase, which drives cAMP synthesis to completion. However, cAMP is rapidly degraded to 5′ AMP by the enzymes phosphodiesterase (PDE), preventing overstimulation of...

Once a ligand binds to a receptor, the signal is transmitted through the membrane and into the cytoplasm. The continuation of a signal in this manner is called signal transduction. Signal transduction only occurs with cell-surface receptors, which cannot interact with most components of the cell, such as DNA. Only internal receptors can interact directly with DNA in the nucleus to initiate protein synthesis. When a ligand binds to its receptor, conformational changes occur that affect the...

6.4K
Cyclic Adenosine Monophosphate (cAMP) is an essential second messenger that activates protein kinase A (PKA) and regulates various biological processes. A single epinephrine molecule binds to GPCR and activates several heterotrimeric G proteins, each stimulating multiple adenylyl cyclase, amplifying the signal, and synthesizing large numbers of cAMP molecules. Small changes in cAMP concentration affect PKA activity. The binding of four cAMP molecules induces a conformational change in PKA,...

5.7K
Plant cells communicate to coordinate their cycle of growth, flowering and fruiting, and activities in roots, shoots, and leaves in response to the changing environmental conditions. Plant signaling is distinct from animal signaling. Plants primarily utilize enzyme-linked receptors, whereas the largest class of cell-surface receptors in animals are G-protein coupled receptors (GPCRs). Unlike animals, receptor tyrosine kinases are rare in plants. Instead, plants have a diverse class of...

01:27C4 Pathway and CAM
45.6K
Most plants use the C3 pathway for carbon fixation. However, some plants, such as sugar cane, corn, and cacti that grow in hot conditions, use alternative pathways to fix carbon and conserve energy loss due to photorespiration. Photorespiration is the process that occurs when the oxygen concentration is high. Under such conditions, the rubisco enzyme in the Calvin cycle binds O2 instead of CO2, which halts photosynthesis and consumes energy.
