The apparent dissociation constant (K d) in the various isolates ranged between 8 and 19 nm; the binding capacity varied from 122 to over 2400 fmol (mg cytosol protein)−1. There was no correlation between the amount or affinity of CBP and isolate virulence for murine hosts. Further analysis revealed demonstrable CBP in six out of six Candida species other than C. albicans. One isolate of C. tropicalis has been identified which fails to bind [3H]corticosterone. Saccharomyces cerevisiae, Neurospora crassa and Paracoccidioides brasiliensis also failed to bind [3H]corticosterone. Preliminary attempts were made to determine functions mediated by CBP in Candida, but in vitro growth, phase conversion and glucose oxidation by Candida were unaffected by the addition of a variety of steroid hormones. These data indicate that the presence of CBP in Candida does not correlate with either virulence or serotype. The physiological significance of CBP remains to be determined.", }
