Complex: Fatty-acyl-CoA synthase
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
- Catalyzes the formation of long-chain fatty acids from acetyl-CoA, malonyl-CoA and NADPH. Consists of a multifunctional enzyme composed of two non-identical alpha and beta subunits which are organized in an alpha6beta6 complex with 6 sites of fatty acid synthesis. The alpha subunit, FAS2, contains domains for acyl carrier protein, 3-oxoacyl-[acyl-carrier-protein] reductase, and 3-oxoacyl-[acyl-carrier-protein] synthase. The beta subunit, FAS 1, contains domains for [acyl-carrier-protein] acetyltransferase and malonyltransferase, S-acyl fatty acid synthase thioesterase, enoyl-[acyl-carrier-protein] reductase, and 3-hydroxypalmitoyl-[acyl-carrier-protein] dehydratase.
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.

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.
