Functional Annotations
Enzyme classification and Gene Ontology terms linked to this protein.
Enzyme Commission (EC)
1Gene Ontology (GO)
6- GO:0005886 The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
- GO:0009055 A molecular function representing the directed movement of electrons from one molecular entity to another, typically mediated by electron carriers or acceptors, resulting in the transfer of energy and/or the reduction-oxidation (redox) transformation of chemical species. This activity is fundamental to various biological processes, including cellular respiration and photosynthesis, as well as numerous enzymatic reactions involved in metabolic pathways.
- GO:0022900 A process in which a series of electron carriers operate together to transfer electrons from donors to any of several different terminal electron acceptors.
- GO:0051536 Binding to an iron-sulfur cluster, a combination of iron and sulfur atoms.
- GO:0051539 Binding to a 4 iron, 4 sulfur (4Fe-4S) cluster; this cluster consists of four iron atoms, with the inorganic sulfur atoms found between the irons and acting as bridging ligands.
- GO:0046872 Binding to a metal ion.

Ligand evidence
Ligands grouped by evidence source. PDB ligands keep the source crystal visible, and loaded crystals can be opened directly in the structure viewer.
Highest-confidence structural evidence: ligands co-crystallized with this exact protein. If the source PDB is loaded in TPW, use Open crystal to inspect it in the structure viewer.
No PDB structure with a co-crystallized ligand found for this exact protein.
Structural evidence inferred from similar proteins. The source crystal indicates where the ligand was observed; the UniProt column identifies the homologous protein carrying that ligand.
Experimental bioactivity from ChEMBL measured directly on this protein. Score = pchembl (−log Ki/IC₅₀; higher = more potent).
No ChEMBL bioactivity data found for this exact protein.
Bioactivity inferred from similar proteins in ChEMBL. Score = pchembl (−log Ki/IC₅₀; higher = more potent).
No ChEMBL hits found through similar proteins.
Proposed virtual-screening candidates from ZINC. Score = Tanimoto similarity to a known binder (0–1; higher = more similar).
