Iron acquisition from transferrin by Candida albicans depends on the reductive pathway.
Knight SA, Vilaire G, Lesuisse E, Dancis A. Knight SA, et al. Infect Immun. 2005 Sep;73(9):5482-92. doi: 10.1128/IAI.73.9.5482-5492.2005. Infect Immun. 2005. PMID: 16113264 Free PMC article.
FRE10 was required for a surface reductase activity and for efficient transferrin iron uptake activity in unbuffered medium. ...The requirement of FTR1 for virulence in a systemic infection model and its role in transferrin iron uptake raise the possibility that tra …

Rim2, a pyrimidine nucleotide exchanger, is needed for iron utilization in mitochondria.
Yoon H, Zhang Y, Pain J, Lyver ER, Lesuisse E, Pain D, Dancis A. Yoon H, et al. Biochem J. 2011 Nov 15;440(1):137-46. doi: 10.1042/BJ20111036. Biochem J. 2011. PMID: 21777202 Free PMC article.
To test this hypothesis, in the present study we used a genetic screen looking for yeast mutants that are synthetically lethal with the mitochondrial iron carriers Mrs3 and Mrs4. ...The results indicate that Rim2 is a pyrimidine exchanger with an additional unique f …

Candida albicans lacking the frataxin homologue: a relevant yeast model for studying the role of frataxin.
Santos R, Buisson N, Knight SA, Dancis A, Camadro JM, Lesuisse E. Santos R, et al. Mol Microbiol. 2004 Oct;54(2):507-19. doi: 10.1111/j.1365-2958.2004.04281.x. Mol Microbiol. 2004. PMID: 15469520
CaYFH1 transcription was strongly induced by iron, which is consistent with a role of CaYfh1 in iron storage. Iron also regulated transcription of CaHEM14 (encoding protoporphyrinogen oxidase) but not that of CaHEM15 (encoding ferrochelatase). ...

Haemin uptake and use as an iron source by Candida albicans: role of CaHMX1-encoded haem oxygenase.
Santos R, Buisson N, Knight S, Dancis A, Camadro JM, Lesuisse E. Santos R, et al. Microbiology. 2003 Mar;149(Pt 3):579-588. doi: 10.1099/mic.0.26108-0. Microbiology. 2003. PMID: 12634327
Haemin uptake kinetics by C. albicans cells showed two phases: a rapid phase of haemin binding (with a K(d) of about 0.2 microM) followed by a slower uptake phase. ...CaHMX1 expression was induced by iron deprivation, by haemin and by a shift of temper …
