Abstract

ABSTRACT A strain of the common mold Stachybotrys chartarum has been isolated from the lung of a child with pulmonary hemorrhage. We report the purification of stachyrase A, a new serine chymotrypsin-like proteinase from S. chartarum . This enzyme cleaves major protease inhibitors, several biologically active peptides, and collagen, all of which are found in the lung.
