A novel N(alpha)-acetyl alanine aminopeptidase from Allomyces arbuscula.

An N(alpha)-acetyl alanine aminopeptidase has been purified from the aquatic fungus Allomyces arbuscula. The apparent molecular mass of the enzyme was estimated to be 280 kDa by gel filtration through calibrated Sephacryl S300 column. In SDS-PAGE, the purified enzyme appeared as a single band of M(r) 80 kDa.
