Catalysis of the reaction: a nucleoside diphosphate + H2O = a nucleotide + phosphate.

Catalysis of the reaction: a nucleoside triphosphate + H2O = nucleoside diphosphate + phosphate.

Catalysis of the reaction: phosphoenolpyruvate + N-acetyl-D-mannosamine + H2O = phosphate + N-acetylneuraminate .

Rab guanyl-nucleotide exchange factor activity

Stimulates the hydrolysis and exchange of guanyl nucleotides by the GTPase Rab.

Catalysis of the reaction: 5,6-dihydrouracil + NADP+ = uracil + NADPH + H+.

The process of removing sections of the primary RNA transcript to remove sequences not present in the mature form of the RNA and joining the remaining sections to form the mature form of the RNA.

A complex of proteins that, in vitro, stimulates intra-Golgi transport; a 13S complex, about 800 kDa in size and consists of at least five polypeptides. In yeast, this complex is called the Sec34/35 complex and is composed of eight subunits (Sec34p, Sec35p, Dor1p, Cod1p, Cod2p, Cod3p, Cod4p, and Cod5p).

Catalysis of the reaction: 2 peroxide radical + 2 H+ = O2 + H2O2.

Catalysis of the phosphorylation of IkappaB, thereby targeting this for proteasomal degradation and allowing the nuclear translocation of kB. Composed of alpha, beta and gamma subunits, the latter not having kinase activity but presumed to play a regulatory role.

A protein serine/threonine kinase that phosphorylates IkappaB, thereby targeting this for proteasomal degradation and allowing the nuclear translocation of kB. Composed of alpha, beta and gamma subunits, the latter not having kinase activity but presumed to play a regulatory role.

Catalysis of the reaction: cholesterol + reduced adrenal ferredoxin + O2 = pregnenolone + 4-methylpentanal + oxidized adrenal ferredoxin + H2O.

The induction by a virus of an immune response in the host.

passive viral induction of host immune response

The unintentional stimulation by a virus of a host defense response to viral infection, as part of the viral infectious cycle.

Catalysis of the reaction: coumarin + O2 + NADPH + H+ = hydroxycoumarin + H2O + NADP+.
