Function and Biology Details

Reactions catalysed:
Glutarate + 2-oxoglutarate + O(2) = (S)-2-hydroxyglutarate + succinate + CO(2)
RX + glutathione = HX + R-S-glutathione
5,10-methylenetetrahydrofolate + dUMP = dihydrofolate + dTMP
Angiotensin II + H(2)O = angiotensin-(1-7) + L-phenylalanine
ATP + nucleoside diphosphate = ADP + nucleoside triphosphate
Acetyl-CoA + a 2-deoxystreptamine antibiotic = CoA + N(3)-acetyl-2-deoxystreptamine antibiotic
ATP + AMP = 2 ADP
Autocatalytic release of the core protein from the N-terminus of the togavirus structural polyprotein by hydrolysis of a -Trp-|-Ser- bond.
(1a) [enzyme]-L-histidine + 2,3-bisphospho-D-glycerate = [enzyme]-N(tau)-phospho-L-histidine + 2/3-phospho-D-glycerate
ATP + protein L-histidine = ADP + protein N-phospho-L-histidine
dUTP + H(2)O = dUMP + diphosphate
ATP + a protein = ADP + a phosphoprotein
Sucrose + ((1->6)-alpha-D-glucosyl)(n) = D-fructose + ((1->6)-alpha-D-glucosyl)(n+1)
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.
Release of N-terminal proline from a peptide.
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.
Acetyl-CoA + L-serine = CoA + O-acetyl-L-serine
(2E,6E)-farnesyl diphosphate + isopentenyl diphosphate = diphosphate + geranylgeranyl diphosphate
NTP + H(2)O = NDP + phosphate
Release of an N-terminal amino acid, Xaa-|-Yaa-, in which Xaa is preferably Leu, but may be other amino acids including Pro although not Arg or Lys, and Yaa may be Pro. Amino acid amides and methyl esters are also readily hydrolyzed, but rates on arylamides are exceedingly low.
Eliminative cleavage of alginate to give oligosaccharides with 4-deoxy-alpha-L-erythro-hex-4-enuronosyl groups at their non-reducing ends and beta-D-mannuronate at their reducing end.
D-xylopyranose = D-xylulose
Arsenate + glutathione + glutaredoxin = arsenite + a glutaredoxin-glutathione disulfide + H(2)O
Hydrolysis of terminal non-reducing beta-D-galactose residues in beta-D-galactosides
ATP + H(2)O = ADP + phosphate
5,6,7,8-tetrahydrofolate + NADP(+) = 7,8-dihydrofolate + NADPH
Geranylgeranyl diphosphate = (+)-copalyl diphosphate
Nucleoside triphosphate + RNA(n) = diphosphate + RNA(n+1)
2 3-phospho-D-glycerate + 2 H(+) = D-ribulose 1,5-bisphosphate + CO(2) + H(2)O
An acyl-[acyl-carrier protein] + NAD(+) = a trans-2,3-dehydroacyl-[acyl-carrier protein] + NADH
(1a) L-cysteine + [enzyme]-cysteine = L-alanine + [enzyme]-S-sulfanylcysteine
