Structural Evidence That Scytalidolisin (Formerly Scytalidopepsin A) Is a Serine-Carboxyl Peptidase of the Sedolisin Family

Scytalidopepsin A, a pepstatin-insensitive acid endopeptidase from the fungus Scytalidium lignicolum was found to be a member of the sedolisin family of serine-carboxyl peptidases through analyses of the amino acid sequences of peptides derived from the reduced, pyridylethylated enzyme by enzymatic digestion. Hence it should be renamed scytalidolisin (or Scytalidium sedolisin).
