Label	Id	Description
steroid 17-alpha-monooxygenase activity	GO_0004508	[Catalysis of the reaction: a steroid + AH2 + O2 = a 17a-hydroxysteroid + A + H2O.]
steroid 21-monooxygenase activity	GO_0004509	[Catalysis of the reaction: a steroid + donor-H2 + O2 = a 21-hydroxysteroid + acceptor + H2O.]
tryptophan 5-monooxygenase activity	GO_0004510	[Catalysis of the reaction: L-tryptophan + tetrahydrobiopterin + O2 = 5-hydroxy-L-tryptophan + 4-alpha-hydroxytetrahydrobiopterin + H2O.]
tyrosine 3-monooxygenase activity	GO_0004511	[Catalysis of the reaction: L-tyrosine + tetrahydrobiopterin + O2 = 3,4-dihydroxy-L-phenylalanine + 4-alpha-hydroxytetrahydrobiopterin + H2O.]
inositol-3-phosphate synthase activity	GO_0004512	[Catalysis of the reaction: D-glucose 6-phosphate = 1D-myo-inositol 3-phosphate. This reaction requires NAD, which dehydrogenates the CHOH group to CO at C-5 of the glucose 6-phosphate, making C-6 into an active methylene, able to condense with the aldehyde at C-1. Finally, the enzyme-bound NADH reconverts C-5 into the CHOH form.]
neolactotetraosylceramide alpha-2,3-sialyltransferase activity	GO_0004513	[Catalysis of the reaction: CMP-N-acetylneuraminate + beta-D-galactosyl-1,4-N-acetyl-beta-D-glucosaminyl-1,3-beta-D-galactosyl-1,4-beta-D-glucosylceramide = CMP + alpha-N-acetylneuraminyl-2,3-beta-D-galactosyl-1,4-N-acetyl-beta-D-glucosaminyl-1,3-beta-D-galactosyl-1,4-D-glucosylceramide.]
sialyltransferase activity	GO_0008373	[Catalysis of the transfer of sialic acid to an acceptor molecule, typically the terminal portions of the sialylated glycolipids (gangliosides) or to the N- or O-linked sugar chains of glycoproteins.]
nicotinate-nucleotide diphosphorylase (carboxylating) activity	GO_0004514	[Catalysis of the reaction: CO(2) + diphosphate + nicotinate D-ribonucleotide = 5-phospho-alpha-D-ribose 1-diphosphate + 2 H(+) + quinolinate.]
nicotinate-nucleotide adenylyltransferase activity	GO_0004515	[Catalysis of the reaction: ATP + nicotinate ribonucleotide = diphosphate + deamido-NAD+.]
nicotinate phosphoribosyltransferase activity	GO_0004516	[Catalysis of the reaction: diphosphate + nicotinate D-ribonucleotide = 5-phospho-alpha-D-ribose 1-diphosphate + H(+) + nicotinate.]
nuclease activity	GO_0004518	[Catalysis of the hydrolysis of ester linkages within nucleic acids.]
hydrolase activity, acting on ester bonds	GO_0016788	[Catalysis of the hydrolysis of any ester bond.]

RNA-DNA hybrid ribonuclease activity	GO_0004523	[Catalysis of the endonucleolytic cleavage of RNA in RNA-DNA hybrids to 5'-phosphomonoesters.]
GO_0004524	GO_0004524
ribonuclease III activity	GO_0004525	[Catalysis of the endonucleolytic cleavage of RNA with 5'-phosphomonoesters and 3'-OH termini; makes two staggered cuts in both strands of dsRNA, leaving a 3' overhang of 2 nt.]
