Plant seed oil bodies, subcellular lipoprotein inclusions providing storage reserves, are composed of a neutral lipid core surrounded by a phospholipid monolayer with several integrated proteins that play a significant role in stabilization of the particles and probably also in lipid mobilization. Oil bodies' proteins are generally very hydrophobic, due to the long uncharged sequences anchoring them into the lipid core, which makes them extremely difficult to handle and to digest successfully.

Membrane Fraction Complexome of Nitrososphaera viennensis with BN-PAGE and Examination of the Archaeal Ammonia Monooxygenase Complex via SDS-Tricine-PAGE

Project description:Information on the files related to the respective experiments can be found in the metadata file titled “Metadata_for_Nviennensis_Experiments.xlsx”. The data found here encompasses three related mass spectrometry experiments: 1.) BN-PAGE: Biomass of Nitrososphaera viennensis grown in a bioreactor was lysed and membrane fractions were harvested using an ultracentrifuge. Membrane proteins were extracted using n-dodecyl-beta-D-maltoside (DDM) and loaded on a 3-12% gradient blue native PAGE gel. Selected bands were cut out and analyzed via mass spectrometry. 2.) SDS-Tricine-PAGE of AMO Band: A band containing a large amount of the ammonia monooxygenase complex (AMO) was denatured and run on a 15% SDS-Tricine-PAGE gel to identify individual subunits. 3.) AmoC from SDS-Tricine-PAGE: A band containing a high amount of AmoC from the SDS-Tricine-PAGE gel was processed with three separate digestive enzymes (trypsin, chymotrypsin, or GluC) to identify unique peptides among the six AmoC homologs found in the genome of N. viennensis.

ALGOMICS - Proteomic profiling of oil bodies isolated from the unicellular green microalga Chlamydomonas reinhardtii: with focus on proteins involved in lipid metabolism

Project description:Oil-bodies are sites of energy storage in many organisms including microalgae. As a first step toward understanding oil accumulation in algae, we took a proteomic approach on purified oil-body fraction from the model microalga Chlamydomonas reinhardtii grown under nitrogen deprivation. Among the 240 proteins (?2 peptides) identified by LC-MS/MS, 33 were putatively involved in metabolism of lipids (mostly acyl-lipids and sterols). Compared to a recently reported Chlamydomonas oil-body proteome, 19 additional proteins of lipid metabolism were identified, including a glycerol 3-phosphate acyltransferase (GPAT), a lysophosphatidic acid acyltransferase (LPAT) and a putative phospholipid:diacylglycerol acyltransferase (PDAT), spanning the key steps of the triacylglycerol synthesis pathway. In addition, proteins putatively involved in deacylation/reacylation, sterol synthesis, lipid signaling and lipid trafficking were found to be associated to the oil body fraction. This dataset thus provides evidence that in Chlamydomonas oil-bodies are not only storage compartments but also are dynamic structures likely to be involved in processes such as oil synthesis, degradation and lipid homeostasis. The proteins identified here should provide useful targets for genetic studies aiming at increasing our understanding of triacyglycerol synthesis and the role of oil-bodies in microalgal cell functions.
