  2. Mitochondrial matrix - Wikipedia

    en.wikipedia.org/wiki/Mitochondrial_matrix

    The mitochondrial matrix contains the mitochondrial DNA, ribosomes, soluble enzymes, small organic molecules, nucleotide cofactors, and inorganic ions. [1] The enzymes in the matrix facilitate reactions responsible for the production of ATP , such as the citric acid cycle , oxidative phosphorylation , oxidation of pyruvate , and the beta ...

  3. Intramembrane protease - Wikipedia

    en.wikipedia.org/wiki/Intramembrane_protease

    There are four groups of intramembrane proteases, distinguished by their catalytic mechanism: [5]. Metalloproteases: Site-2 protease (S2P) and S2P-like proteases [9]; Aspartyl proteases: this group includes presenilin, the active subunit of gamma secretase [10] [11] and signal peptide peptidases (SPPs) and SPP-like proteases, which are distantly related to presenilin but have opposite membrane ...

  4. Voltage-gated ion channel - Wikipedia

    en.wikipedia.org/wiki/Voltage-gated_ion_channel

    Voltage-gated ion-channels are usually ion-specific, and channels specific to sodium (Na +), potassium (K +), calcium (Ca 2+), and chloride (Cl −) ions have been identified. [1] The opening and closing of the channels are triggered by changing ion concentration, and hence charge gradient, between the sides of the cell membrane.

  5. Protein metabolism - Wikipedia

    en.wikipedia.org/wiki/Protein_metabolism

    Protein metabolism denotes the various biochemical processes responsible for the synthesis of proteins and amino acids (anabolism), and the breakdown of proteins by catabolism. The steps of protein synthesis include transcription, translation, and post translational modifications.

  8. Ribbon diagram - Wikipedia

    en.wikipedia.org/wiki/Ribbon_diagram

    Ribbon diagrams, also known as Richardson diagrams, are 3D schematic representations of protein structure and are one of the most common methods of protein depiction used today. The ribbon depicts the general course and organization of the protein backbone in 3D and serves as a visual framework for hanging details of the entire atomic structure ...
