Complex: 54S mitochondrial large ribosomal subunit

Macromolecular complex annotations are imported from the Complex Portal. These annotations have been derived from physical molecular interaction evidence extracted from the literature and cross-referenced in the entry, or by curator inference from information on homologs in closely related species or by inference from scientific background.

Description
Component of the ribosome, the site of protein biosynthesis resulting from translation of messenger RNA (mRNA). Responsible for the catalytic activity of the ribosome, the peptidyltransferase activity required to catalyze peptide bond formation. The mitochondrial ribosome (mitoribosome) is responsible for the synthesis of mitochondrial genome-encoded proteins, including at least some of the essential transmembrane subunits of the mitochondrial respiratory chain. The mitoribosomes are tethered to the mitochondrial inner membrane and translation products are cotranslationally integrated into the membrane. The inner membrane protein MBA1 (P38300) aligns the mitochondrial peptide exit tunnel with the membrane insertion machinery and supports the transfer of the mitochondrial nascent peptides towards the membrane

Complex Diagram

This diagram displays the protein subunits (blue) of the complex and how they interact with each other. Interactions with other relevant participants such as small molecules (purple), sub-complexes (yellow), and other subunits (red) are also shown. If a participant appears in the diagram with no lines connected to it, then its specific interactions with other participants are currently unknown.

Subunits

This table lists all participants of the complex (proteins, small molecules, nucleic acids, etc.) and their respective stoichiometry. A brief description is also provided for each participant in the table.

Increase the total number of rows showing on this page by using the pull-down located below the table, or use the page scroll at the table's top right to browse through its pages; use the arrows to the right of a column header to sort by that column; filter the table using the "Filter" box at the top of the table.

Gene Ontology

Gene Ontology (GO) terms that describe the function of a complex, the biological process in which it participates, or its cellular location. Click on a term for its definition and other objects annotated to that term.

Shared Annotations

This diagram displays Gene Ontology terms (green) and subunits (blue) that are shared between the given macromolecular complex (black) and other yeast complexes (yellow). The shared GO terms or subunits can be visualized separately using the radio button at the bottom of the graph. Note: No diagram is shown ("No shared annotations") if there are less than 2 shared annotations (either GO terms or subunits of other complexes) between this complex and any other complexes.
