Transport proteins (carriers) of mitochondria [PDF]

open access: yesIUBMB Life, 2008
AbstractMitochondria are subcellular structures essential to the aerobic eukaryotic cell. Their role extends much beyond their basic reactions of oxidative phosphorylation. It encompasses the steps critical for cellular metabolic pathways, for apoptosis, and for other processes such as antiviral signaling.

Transport of proteins into mitochondria [PDF]

open access: yes, 1985
The transfer of cytoplasmically synthesized precursor proteins into or across the inner mitochondrial membrane is dependent on energization of the membrane.

A novel approach for measuring sphingosine-1-phosphate and lysophosphatidic acid binding to carrier proteins using monoclonal antibodies and the Kinetic Exclusion Assay

open access: yesJournal of Lipid Research, 2016
Sphingosine-1-phosphate (S1P) and lysophosphatidic acid (LPA) are bioactive signaling lysophospholipids that activate specific G protein-coupled receptors on the cell surface triggering numerous biological events.

Efficient processing of an antigenic sequence for presentation by MHC class I molecules depends on its neighboring residues in the protein [PDF]

open access: yes, 1991
Processing of endogenously synthesized proteins generates short peptides that are presented by MHC class I molecules to CD8 T lymphocytes. Here it is documented that not only the sequence of the presented peptide but also the residues by which it is ...

Using small molecules to facilitate exchange of bicarbonate and chloride anions across liposomal membranes [PDF]

open access: yes, 2009
Bicarbonate is involved in a wide range of biological processes, which include respiration, regulation of intracellular pH and fertilization. In this study we use a combination of NMR spectroscopy and ion-selective electrode techniques to show that the ...

A Review of Whey Protein-Based Bioactive Delivery Systems: Design, Fabrication, and Application

open access: yesFoods
The efficacy of many edible bioactive agents is limited by their low water dispersibility and chemical instability in foods, as well as by their poor bioaccessibility, low absorption, and metabolism within the human gastrointestinal tract.

Gating mechanism of elongating β-ketoacyl-ACP synthases. [PDF]

open access: yes, 2020
Carbon-carbon bond forming reactions are essential transformations in natural product biosynthesis. During de novo fatty acid and polyketide biosynthesis, β-ketoacyl-acyl carrier protein (ACP) synthases (KS), catalyze this process via a decarboxylative ...

Hemelipoglycoprotein from the ornate sheep tick, dermacentor marginatus: structural and functional characterization

open access: yesParasites & Vectors, 2011
Background Tick carrier proteins are able to bind, transport, and store host-blood heme, and thus they function also as antioxidants. Nevertheless, the role of carrier proteins in ticks is not fully understood.

Distinct steps in the import of ADP/ATP carrier into mitochondria [PDF]

open access: yes, 1987
Transport of the precursor to the ADP/ATP carrier from the cytosol into the mitochondrial inner membrane was resolved into several consecutive steps. The precursor protein was trapped at distinct stages of the import pathway and subsequently chased to ...

Biosynthesis of Mitochondrial Porin and Insertion into the Outer Mitochondrial Membrane of Neuruspora crassa [PDF]

open access: yes, 1982
Mitochondrial porin, the major protein of the outer mitochondrial membrane is synthesized by free cytoplasmic polysomes. The apparent molecular weight of the porin synthesized in homologous or heterologous cell-free systems is the same as that of the ...
