Function and Biology Details

Reactions catalysed:
L-threonine + ATP + HCO(3)(-) = L-threonylcarbamoyladenylate + diphosphate + H(2)O
(1a) S-adenosyl-L-methionine + [protein]-L-arginine = S-adenosyl-L-homocysteine + [protein]-N(omega)-methyl-L-arginine
Hydrolysis of terminal, non-reducing branched (1->3)-alpha-D-galactosidic residues, producing free D-galactose
A carboxylic ester + H(2)O = an alcohol + a carboxylate
Hydrolysis of alpha-(2->3)-, alpha-(2->6)-, alpha-(2->8)- glycosidic linkages of terminal sialic acid residues in oligosaccharides, glycoproteins, glycolipids, colominic acid and synthetic substrates.
Selective hydrolysis of -Xaa-Xaa-|-Yaa- bonds in which each of the Xaa can be either Arg or Lys and Yaa can be either Ser or Ala.
Hydrolysis of four peptide bonds in the viral precursor polyprotein, commonly with Asp or Glu in the P6 position, Cys or Thr in P1 and Ser or Ala in P1'.
5,10-methylenetetrahydrofolate + dUMP = dihydrofolate + dTMP
1-(5-phospho-beta-D-ribosyl)-ATP + diphosphate = ATP + 5-phospho-alpha-D-ribose 1-diphosphate
Nitric oxide + H(2)O + ferricytochrome c = nitrite + ferrocytochrome c + 2 H(+)
ATP + pyridoxal = ADP + pyridoxal 5'-phosphate
ATP + 1D-myo-inositol 1,3,4,5,6-pentakisphosphate = ADP + 1D-myo-inositol hexakisphosphate
ATP + H(2)O + cellular protein(Side 1) = ADP + phosphate + cellular protein(Side 2)
Selective cleavage of Gln-|-Gly bond in the poliovirus polyprotein. In other picornavirus reactions Glu may be substituted for Gln, and Ser or Thr for Gly.
Selective cleavage of Tyr-|-Gly bond in picornavirus polyprotein.
RH + [reduced NADPH--hemoprotein reductase] + O(2) = ROH + [oxidized NADPH--hemoprotein reductase] + H(2)O
NTP + H(2)O = NDP + phosphate
N-carbamoylputrescine + H(2)O = putrescine + CO(2) + NH(3)
Hydrolysis of terminal, non-reducing alpha-D-galactose residues in alpha-D-galactosides, including galactose oligosaccharides, galactomannans and galactolipids
Cleaves -Ala-|-Ser- and -Ala-|-Ala- bonds in the scaffold protein.
ATP + H(2)O = ADP + phosphate
4 Fe(2+) + 4 H(+) + O(2) = 4 Fe(3+) + 2 H(2)O
5,6,7,8-tetrahydrofolate + NADP(+) = 7,8-dihydrofolate + NADPH
Isocitrate = succinate + glyoxylate
A chalcone = a flavanone
4 benzenediol + O(2) = 4 benzosemiquinone + 2 H(2)O
Nucleoside triphosphate + RNA(n) = diphosphate + RNA(n+1)
Hydrolyzes single-stranded DNA or mismatched double-stranded DNA and polynucleotides, releasing free uracil
S-formylglutathione + H(2)O = glutathione + formate
