Functional Annotations

Enzyme classification and Gene Ontology terms linked to this protein.

8 GO

Gene Ontology (GO)

8
  • GO:0030976 Binding to thiamine pyrophosphate, the diphosphoric ester of thiamine. Acts as a coenzyme of several (de)carboxylases, transketolases, and alpha-oxoacid dehydrogenases.
  • 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.
  • GO:0000287 Binding to a magnesium (Mg) ion.
  • GO:0005948 A dimeric (a large and a small chain) or tetrameric (two large and two small chains) enzyme complex. Catalyzes the formation of acetolactate from pyruvate.
  • GO:0003984 Catalysis of the reaction: H+ + 2 pyruvate = (2S)-2-acetolactate + CO2. Can also convert 2-oxobutanoate and pyruvate to (S)-2-ethyl-2-hydroxy-3-oxobutanoate.
  • GO:0050660 Binding to FAD, flavin-adenine dinucleotide, the coenzyme or the prosthetic group of various flavoprotein oxidoreductase enzymes, in either the oxidized form, FAD, or the reduced form, FADH2.
  • GO:0009097 OBSOLETE. The chemical reactions and pathways resulting in the formation of isoleucine, (2R*,3R*)-2-amino-3-methylpentanoic acid.
  • GO:0009099 The chemical reactions and pathways resulting in the formation of valine, 2-amino-3-methylbutanoic acid.

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.

89 records

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.
