Catalysis of the reaction: orotidine 5'-phosphate + diphosphate = orotate + 5-phospho-alpha-D-ribose 1-diphosphate.

Catalysis of the transfer of a phosphate group from GTP or GDP to a mannose molecule.

Catalysis of the integration of lambdoid phage DNA during establishment, probably by forming a transient DNA-protein link.

The directed movement of choline into, out of, within or between cells. Choline (2-hydroxyethyltrimethylammonium) is an amino alcohol that occurs widely in living organisms as a constituent of certain types of phospholipids and in the neurotransmitter acetylcholine.

Catalysis of the hydrolysis of the terminal 1,2-linked alpha-D-mannose residues in the oligo-mannose oligosaccharide Man(9)(GlcNAc)(2).

The directed movement of dopamine into, out of, within or between cells. Dopamine is a catecholamine neurotransmitter and a metabolic precursor of noradrenaline and adrenaline.

Catalysis of the hydrolysis of the terminal 1,3- and 1,6-linked alpha-D-mannose residues in the mannosyl-oligosaccharide Man(5)(GlcNAc)(3).

mannosyl-oligosaccharide glucosidase (processing A-glucosidase I) activity

Catalysis of the exohydrolysis of the non-reducing terminal glucose residue in the mannosyl-oligosaccharide Glc(3)Man(9)GlcNAc(2).

Catalysis of the transfer of a oligosaccharyl group to an acceptor molecule, typically another carbohydrate or a lipid.

The switching of activated B cells from IgM biosynthesis to biosynthesis of an IgA isotype, accomplished through a recombination process involving an intrachromosomal deletion between switch regions that reside 5' of the IgM and one of the IgA constant region gene segments in the immunoglobulin heavy chain locus.

The chemical reactions involving a deoxyribonucleoside triphosphate, a glycosamine consisting of a base linked to a deoxyribose sugar esterified with triphosphate on its glycose moiety.

The process whereby new strands of DNA are synthesized. The template for replication can either be DNA or RNA.

Catalysis of the reaction: GDP-mannose + chitobiosyldiphosphodolichol = GDP + beta-D-mannosylchitobiosyldiphosphodolichol.
