MF

metalloendopeptidase activity

Catalysis of the hydrolysis of internal, alpha-peptide bonds in a polypeptide chain by a mechanism in which water acts as a nucleophile, one or two metal ions hold the water molecule in place, and charged amino acid side chains are ligands for the metal i

GO:0005618

CC

cell wall

The rigid or semi-rigid envelope lying outside the cell membrane of plant, fungal, most prokaryotic cells and some protozoan parasites, maintaining their shape and protecting them from osmotic lysis. In plants it is made of cellulose and, often, lignin; i

GO:0005730

CC

nucleolus

A small, dense body one or more of which are present in the nucleus of eukaryotic cells. It is rich in RNA and protein, is not bounded by a limiting membrane, and is not seen during mitosis. Its prime function is the transcription of the nucleolar DNA int

GO:0005739

CC

mitochondrion

A semiautonomous, self replicating organelle that occurs in varying numbers, shapes, and sizes in the cytoplasm of virtually all eukaryotic cells. It is notably the site of tissue respiration.

GO:0005741

CC

mitochondrial outer membrane

The outer, i.e. cytoplasm-facing, lipid bilayer of the mitochondrial envelope.

GO:0005743

CC

mitochondrial inner membrane

The inner, i.e. lumen-facing, lipid bilayer of the mitochondrial envelope. It is highly folded to form cristae.

GO:0005750

CC

mitochondrial respiratory chain complex III

A protein complex located in the mitochondrial inner membrane that forms part of the mitochondrial respiratory chain. Contains about 10 polypeptide subunits including four redox centers: cytochrome b/b6, cytochrome c1 and an 2Fe-2S cluster. Catalyzes the

GO:0005758

CC

mitochondrial intermembrane space

The region between the inner and outer lipid bilayers of the mitochondrial envelope.

GO:0005759

CC

mitochondrial matrix

The gel-like material, with considerable fine structure, that lies in the matrix space, or lumen, of a mitochondrion. It contains the enzymes of the tricarboxylic acid cycle and, in some organisms, the enzymes concerned with fatty acid oxidation.

GO:0005774

CC

vacuolar membrane

The lipid bilayer surrounding the vacuole and separating its contents from the cytoplasm of the cell.

GO:0006122

BP

mitochondrial electron transport, ubiquinol to cytochrome c

The transfer of electrons from ubiquinol to cytochrome c that occurs during oxidative phosphorylation, mediated by the multisubunit enzyme known as complex III.

GO:0006508

BP

proteolysis

The hydrolysis of proteins into smaller polypeptides and/or amino acids by cleavage of their peptide bonds.

GO:0008270

MF

zinc ion binding

Interacting selectively and non-covalently with zinc (Zn) ions.

GO:0009060

BP

aerobic respiration

The enzymatic release of energy from inorganic and organic compounds (especially carbohydrates and fats) which requires oxygen as the terminal electron acceptor.

GO:0009507

CC

chloroplast

A chlorophyll-containing plastid with thylakoids organized into grana and frets, or stroma thylakoids, and embedded in a stroma.

GO:0016020

CC

membrane

A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.

GO:0016485

BP

protein processing

Any protein maturation process achieved by the cleavage of a peptide bond or bonds within a protein. Protein maturation is the process leading to the attainment of the full functional capacity of a protein.

GO:0016491

MF

oxidoreductase activity

Catalysis of an oxidation-reduction (redox) reaction, a reversible chemical reaction in which the oxidation state of an atom or atoms within a molecule is altered. One substrate acts as a hydrogen or electron donor and becomes oxidized, while the other ac
