Catalysis of the reaction: acetyl-CoA + choline = CoA + O-acetylcholine.

The process whose specific outcome is the progression of the notochord over time, from its formation to the mature structure. The notochord is a mesoderm-derived structure located ventral of the developing nerve cord. In vertebrates, the notochord serves as a core around which other mesodermal cells form the vertebrae. In the most primitive chordates, which lack vertebrae, the notochord persists as a substitute for a vertebral column.

Catalysis of the reaction: ATP + choline = ADP + O-phosphocholine.

A conserved multimeric membrane-associated complex involved in retrograde transport from endosomes to the Golgi apparatus. For example, the budding yeast retromer comprises Vps35p, Vps29p, Vps26p, Vps5p, and Vps17p.

Catalysis of the reaction: an acylcholine + H2O = choline + a carboxylic acid anion.

Catalysis of the reaction: CTP + choline phosphate = diphosphate + CDP-choline.

Catalysis of the reaction: chorismate = prephenate.

Catalysis of the reaction: 5-O-(1-carboxyvinyl)-3-phosphoshikimate = chorismate + phosphate.

The post-translational removal of peptide sequences from within a protein sequence.

Catalysis of the reaction: acetyl-CoA + H2O + oxaloacetate = citrate + CoA.

Catalysis of the reaction: coproporphyrinogen-III + O2 + 2 H+ = protoporphyrinogen-IX + 2 CO2 + 2 H2O.

The switching of activated B cells from IgM biosynthesis to biosynthesis of other isotypes of immunoglobulin, accomplished through a recombination process involving an intrachromosomal deletion involving switch regions that reside 5' of each constant region gene segment in the immunoglobulin heavy chain locus.

Any process that modulates the frequency, rate or extent of isotype switching.

The breakdown into simpler components of low-density lipoproteins, also known as beta lipoproteins, one of the classes of lipoproteins found in the bloodstream of animals, acting as a carrier for cholesterol and fats.
