Function and Biology Details
L-cystathionine + H(2)O = L-homocysteine + NH(3) + pyruvate
5,10-methylenetetrahydrofolate + dUMP = dihydrofolate + dTMP
(1a) L-cystathionine = L-cysteine + 2-aminobut-2-enoate
S-adenosyl 3-(methylthio)propylamine + putrescine = 5'-S-methyl-5'-thioadenosine + spermidine
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.
L-glutamate + H(2)O + NADP(+) = 2-oxoglutarate + NH(3) + NADPH
Nucleoside triphosphate + RNA(n) = diphosphate + RNA(n+1)
Hydrolysis of (1->4)-beta-linkages between N-acetylmuramic acid and N-acetyl-D-glucosamine residues in a peptidoglycan and between N-acetyl-D-glucosamine residues in chitodextrins
ATP + a protein = ADP + a phosphoprotein
TSAVLQ-|-SGFRK-NH(2) and SGVTFQ-|-GKFKK the two peptides corresponding to the two self-cleavage sites of the SARS 3C-like proteinase are the two most reactive peptide substrates. The enzyme exhibits a strong preference for substrates containing Gln at P1 position and Leu at P2 position.
Catechol + O(2) = cis,cis-muconate
(S)-dihydroorotate + fumarate = orotate + succinate
Selective cleavage of Tyr-|-Gly bond in picornavirus polyprotein.
NTP + H(2)O = NDP + phosphate
Pyruvate + L-aspartate-4-semialdehyde = (4S)-4-hydroxy-2,3,4,5-tetrahydro-(2S)-dipicolinate + H(2)O
Isochorismate + H(2)O = (2S,3S)-2,3-dihydroxy-2,3-dihydrobenzoate + pyruvate
N-carbamoylputrescine + H(2)O = putrescine + CO(2) + NH(3)
(S)-malate = fumarate + H(2)O
A phosphate monoester + H(2)O = an alcohol + phosphate
2'-deoxyribonucleoside diphosphate + thioredoxin disulfide + H(2)O = ribonucleoside diphosphate + thioredoxin
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.
Endohydrolysis of RNA in RNA/DNA hybrids. Three different cleavage modes: 1. sequence-specific internal cleavage of RNA. Human immunodeficiency virus type 1 and Moloney murine leukemia virus enzymes prefer to cleave the RNA strand one nucleotide away from the RNA-DNA junction. 2. RNA 5'-end directed cleavage 13-19 nucleotides from the RNA end. 3. DNA 3'-end directed cleavage 15-20 nucleotides away from the primer terminus.
4 Fe(2+) + 4 H(+) + O(2) = 4 Fe(3+) + 2 H(2)O
5,6,7,8-tetrahydrofolate + NADP(+) = 7,8-dihydrofolate + NADPH
3'-end directed exonucleolytic cleavage of viral RNA-DNA hybrid
Thiol-dependent hydrolysis of ester, thioester, amide, peptide and isopeptide bonds formed by the C-terminal Gly of ubiquitin (a 76-residue protein attached to proteins as an intracellular targeting signal).
The C-O-P bond 3' to the apurinic or apyrimidinic site in DNA is broken by a beta-elimination reaction, leaving a 3'-terminal unsaturated sugar and a product with a terminal 5'-phosphate
Deoxynucleoside triphosphate + DNA(n) = diphosphate + DNA(n+1)
