GO

GO:0005829 The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes. GO:0008732 Catalysis of the reaction: L-allo-threonine = glycine + acetaldehyde. GO:0006545 The chemical reactions and pathways resulting in the formation of glycine, aminoethanoic acid. GO:0006567 The chemical reactions and pathways resulting in the breakdown of L-threonine. GO:0006520 The chemical reactions and pathways involving amino acids, carboxylic acids containing one or more amino groups. GO:0016829 Catalysis of the cleavage of C-C, C-O, C-N and other bonds by other means than by hydrolysis or oxidation, or conversely adding a group to a double bond. They differ from other enzymes in that two substrates are involved in one reaction direction, but only one in the other direction. When acting on the single substrate, a molecule is eliminated and this generates either a new double bond or a new ring.

Selected Druggability evidence

Selected Druggability is the FPocket score chosen for ranking using the curated structure priority. The 3D viewer may show a different loaded structure, so its visible pockets can differ.

GO:0003824 Catalysis of a biochemical reaction at physiological temperatures. In biologically catalyzed reactions, the reactants are known as substrates, and the catalysts are naturally occurring macromolecular substances known as enzymes. Enzymes possess specific binding sites for substrates, and are usually composed wholly or largely of protein, but RNA that has catalytic activity (ribozyme) is often also regarded as enzymatic.

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.

8 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.
