Wall formation by Candida albicans yeast cells: synthesis, secretion and incorporation of two types of mannoproteins.

1993

SUMMARY: The mannoprotein components solubilized from the walls of Candida albicans blastoconidia following degradation of the glucan network with β-glucanase (Zymolyase) have higher molecular masses than their probable precursors present in the supernatant of regenerating protoplasts. It therefore appears that the mannoproteins are released from the walls as part of supramolecular complexes. Immunological analysis using both polyclonal and monoclonal antibodies has demonstrated the probable relationship between molecules found in a mixed membrane preparation, those secreted by regenerating protoplasts, and those present in yeast cell walls. Some mannoproteins secreted by protoplasts incuba…
