Covalent association of beta-1,3-glucan with beta-1,6-glucosylated mannoproteins in cell walls of Candida albicans.

abstract：:The dimorphic fungus Mucor racemosus was found to contain the cyclic nucleotide guanosine 3',5'-monophosphate (cGMP). Approximately equivalent amounts of the compound were found in ungerminated spores, yeastlike cells, and mycelia. Germinating spores contained severalfold higher amounts of cGMP than the other cell for...
