Function and Biology Details

Reactions catalysed:
Diphosphate + H(2)O = 2 phosphate
Cleaves proteins of the adenovirus and its host cell at two consensus sites: -Yaa-Xaa-Gly-Gly-|-Xaa- and -Yaa-Xaa-Gly-Xaa-|-Gly- (in which Yaa is Met, Ile or Leu, and Xaa is any amino acid).
L-asparagine + H(2)O = L-aspartate + NH(3)
Nitric oxide + H(2)O + ferricytochrome c = nitrite + ferrocytochrome c + 2 H(+)
ATP + H(2)O = ADP + phosphate
NTP + H(2)O = NDP + phosphate
4 Fe(2+) + 4 H(+) + O(2) = 4 Fe(3+) + 2 H(2)O
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.
Acetyl-CoA + [protein]-L-lysine = CoA + [protein]-N(6)-acetyl-L-lysine
Nucleoside triphosphate + RNA(n) = diphosphate + RNA(n+1)
CoA-(4'-phosphopantetheine) + apo-[acyl-carrier-protein] = adenosine 3',5'-bisphosphate + holo-[acyl-carrier-protein]
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.
Selective cleavage of Tyr-|-Gly bond in picornavirus polyprotein.
Pyruvate + L-aspartate-4-semialdehyde = (4S)-4-hydroxy-2,3,4,5-tetrahydro-(2S)-dipicolinate + H(2)O
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'.
S-formylglutathione + H(2)O = glutathione + formate
