Herein, we discuss the role of the native cysteines present in a major multidrug ABC transporter of Candida albicans, Cdr1p, and describe the construction of this transporter's functional cysteine-less (cysless) protein version for cross-linking studies. In the experiments in which all 23 cysteines were replaced individually, we observed that most of the cysteine replacements were tolerated by the protein, but the replacement of C1056, C1091, C1106, C1294 or C1336 resulted in an enhanced drug susceptibility together with an abrogated drug efflux. Notably, the ATPase activity was uncoupled, which largely remained unaffected in these variants.

In the present work, we investigated the antifungal activity of two de novo designed, antimicrobial peptides VS2 and VS3, incorporating unnatural amino acid α,β-dehydrophenylalanine (ΔPhe). We observed that the low-hemolytic peptides could irreversibly inhibit the growth of various Candida species and multidrug resistance strains at MIC(80) values ranging from 15.62 μM to 250 μM.
