Isolation of antigens with proteolytic activity from Coccidioides immitis.
Three antigens with proteolytic activity have been isolated from crude, water-soluble fractions of the saprobic phase of the fungal pathogen Coccidioides immitis. Two proteinases, identified in our immunoelectrophoresis reference system as Ag11 and AgCS, were isolated from the soluble conidial wall fraction (SCWF). Ag11 was previously shown to be a serine proteinase and was characterized in thi...
متن کاملCollagenolytic activity of Coccidioides immitis.
Coccidioides immitis appears to be unable to digest particulate collagen when cultured on collagen-containing semisolid culture media. However, all C. immitis strains solubilized collagen when the fungus was grown in liquid suspension cultures. Moreover, sterile culture filtrates were collagenolytic in collagen-buffer-agar plate assays.
متن کاملIsolation and characterization of an extracellular proteinase of Coccidioides immitis.
A proteinase isolated from the respiratory pathogen, Coccidioides immitis, was shown to have collagenolytic and elastinolytic activity, as well as the ability to cleave human serum immunoglobulin G and secretory immunoglobulin A. Proteolytic activity was demonstrated with a bovine casein digestion assay in conidial culture exudates, mycelial and spherule culture filtrates, conidial and spherule...

Bacteriol. 82:714-723. 1961.-Soluble polysaccharide from mycelia or culture filtrates of Coccidioides immitis was found to consist mainly of mannose, but also included small quantities of galactose and another reducing sugar. Isolation of the polysaccharide by etha...
متن کاملUnusual reducing sugar from Coccidioides immitis.
Documentation is offered for the identification of 3-O-methyl-mannose as one of several neutral sugars found in defatted arthrospore and mycelial cell walls of Coccidioides immitis.
