3.4.22.44: nuclear-inclusion-a endopeptidase

This is an abbreviated version, for detailed information about nuclear-inclusion-a endopeptidase, go to the full flat file.

Reaction

Hydrolyses glutaminyl bonds, and activity is further restricted by preferences for the amino acids in P6 - P1' that vary with the species of potyvirus, e.g. Glu-Xaa-Xaa-Tyr-Xaa-Gln-/-(Ser or Gly) for the enzyme from tobacco etch virus. The natural substrate is the viral polyprotein, but other proteins and oligopeptides containing the appropriate consensus sequence are also cleaved. =
