1.1.2.8

GO:0016020 A lipid bilayer along with all the proteins and protein complexes embedded in it and attached to it. GO:0030288 The region between the inner (cytoplasmic or plasma) membrane and outer membrane of organisms with two membranes such as Gram negative bacteria. These periplasmic spaces are relatively thick and contain a thin peptidoglycan layer (PGL), also referred to as a thin cell wall. GO:0052934 Catalysis of the reaction: 2 [Fe(III)cytochrome c] + a primary alcohol = 2 [Fe(II)cytochrome c] + an aldehyde + 2 H+. GO:0005509 Binding to a calcium ion (Ca2+). GO:0020037 Binding to a heme, a compound composed of iron complexed in a porphyrin (tetrapyrrole) ring. GO:0070968 Binding to pyrroloquinoline quinone, PQQ, the coenzyme or the prosthetic group of certain alcohol dehydrogenases and glucose dehydrogenases.

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.

52 records

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.
