Function and Biology Details

Reactions catalysed:
Phosphatidylinositol 3,4,5-trisphosphate + H(2)O = phosphatidylinositol 4,5-bisphosphate + phosphate
5,10-methylenetetrahydrofolate + dUMP = dihydrofolate + dTMP
4-phosphonooxy-L-threonine + 2-oxoglutarate = (3R)-3-hydroxy-2-oxo-4-phosphonooxybutanoate + L-glutamate
L-glutamate + H(2)O + NADP(+) = 2-oxoglutarate + NH(3) + NADPH
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 proteins with broad specificity for peptide bonds, and a preference for a large uncharged residue in P1. Hydrolyzes peptide amides.
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.
NTP + H(2)O = NDP + phosphate
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.
Hydrolyzes poly(ADP-D-ribose) at glycosidic (1''-2') linkage of ribose-ribose bond to produce free ADP-D-ribose
[a protein]-serine/threonine phosphate + H(2)O = [a protein]-serine/threonine + phosphate
L-histidinol phosphate + H(2)O = L-histidinol + phosphate
1-deoxy-D-xylulose 5-phosphate + 2-iminoacetate + thiocarboxy-[sulfur-carrier protein ThiS] = 2-((2R,5Z)-2-carboxy-4-methylthiazol-5(2H)-ylidene)ethyl phosphate + [sulfur-carrier protein ThiS] + 2 H(2)O
5,10-methylenetetrahydrofolate + glycine + H(2)O = tetrahydrofolate + L-serine
ATP + H(2)O = ADP + phosphate
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.
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).
A beta-lactam + H(2)O = a substituted beta-amino acid
Protein tyrosine phosphate + H(2)O = protein tyrosine + phosphate
Deoxynucleoside triphosphate + DNA(n) = diphosphate + DNA(n+1)
ATP + L-aspartate = ADP + 4-phospho-L-aspartate
