- Any protein with one or more saccharide or oligosaccharide chains covalently linked to amino acid side chains. Most secreted proteins and most proteins exposed on the outer surface of the plasma membrane are glycoproteins.
- The space inside a hollow structure. In cells: the cavity enclosed by an organelle membrane. In tissues: the cavity enclosed by a sheet of cells.
- Transport of proteins from one cell compartment to another by means of membrane-bounded intermediaries such as vesicles or organelle fragments.
- Mitochondrial membrane that encloses the matrix space and forms extensive invaginations called cristae.
- Protein-sorting signal that consists of a specific three-dimensional arrangement of atoms on the folded protein's surface.
- Membrane-bound protein that mediates the transport of another protein across a membrane.
- T/F: The TOM complex is required for the import of all nucleus-encoded mitochondrial proteins.
- Short amino acid sequence that enables a polypeptide chain to start being translocated across the endoplasmic reticulum membrane through a protein translocator. Multipass membrane proteins sometimes have both N-terminal (signal sequence) and internal start-transfer signals
- Compartment of mitochondrion between by the outer and inner mitochondrial membranes.
- Sorting signal contained in the structure of macromolecules and complexes that are transported from the nucleus to the cytosol through the nuclear pore complex.
- Hydrophobic amino acid sequence that halts translocation of a polypeptide chain through the endoplasmic reticulum membrane, thus anchoring the protein chain in the membrane
- Protein translocator that helps β-barrel proteins to fold properly in the outer mitochondrial membrane.
- T/F: Some proteins are kept out of the nucleus, until needed, by inactivating their nuclear localization signals (NLSs) by phosphorylation.
- "Bedding": the connective tissue in which a glandular or other epithelium is embedded. Stromal cells provide the environment necessary for the development of other cells within the tissue. (2) The large interior space of a chloroplast, containing enzymes that incorporate CO2 into sugars.
- Component in the endoplasmic reticulum (ER) membrane that guides the signal recognition particle to the ER membrane.
- Conjugate (12 total)2. Nosotros ______ enseguida. (dormirse)
- Process of transferring a single saccharide or preformed precursor oligosaccharide to proteins.
- Movement of proteins between the cytosol and the nucleus through nuclear pore complexes in the nuclear envelope that function as selective gates.
- T/F: All cytosolic proteins have nuclear export signals that allow them to be removed from the nucleus when it reassembles after mitosis.
- Signal sequence or signal patch that directs the delivery of a protein to a specific location, such as a particular intracellular compartment.
