Enables the directed movement of norepinephrine into, out of, within or between cells. Norepinephrine (3,4-dihydroxyphenyl-2-aminoethanol) is a hormone secreted by the adrenal medulla and a neurotransmitter in the sympathetic peripheral nervous system and in some tracts of the CNS. It is also the biosynthetic precursor of epinephrine.

Catalysis of the reaction: norepinephrine(out) + Na+(out) = norepinephrine(in) + Na+(in).

Catalysis of the reaction: serotonin(out) + Na+(out) = serotonin(in) + Na+(in).

Enables the directed movement of a nucleoside, a nucleobase linked to either beta-D-ribofuranose (ribonucleoside) or 2-deoxy-beta-D-ribofuranose, (a deoxyribonucleotide), into, out of, within or between cells.

Enables the directed movement of nucleotide-sugars into, out of, within or between cells. A nucleotide-sugars is any nucleotide in which the distal phosphoric residue of a nucleoside 5'-diphosphate is in glycosidic linkage with a monosaccharide or monosaccharide derivative.

Catalysis of the reaction: (S)-2,3-epoxysqualene = lanosterol. This is a cyclization reaction that forms the sterol nucleus.

The breakdown into simpler components of estrogens, C18 steroid hormones that can stimulate the development of female sexual characteristics. Also found in plants.

Catalysis of the reaction: 4,4-dimethyl-5-alpha-cholesta-8,24-dien-3-beta-ol + NAD(P)H + H+ + O2 = 4-beta-hydroxymethyl-4-alpha-methyl-5-alpha-cholesta-8,24-dien-3-beta-ol + NAD(P)+ + H2O.

RNA polymerase II transcription elongation factor activity

Pol II transcription elongation factor activity

Catalysis of the reaction: a nitrile + H2O = a carboxylate + NH3. Acts on a wide range of aromatic nitriles including (indole-3-yl)-acetonitrile and some aliphatic nitriles, and on the corresponding acid amides.

Catalysis of the reaction: phenylpyruvate + L-glutamine = L-phenylalanine + 2-keto-glutaramate.
