Figure 1.
Sequence alignment of Saccharomyces cerevisiae lanosterol 14-α demethylase with six Mucorales CYP51s. R. arrhizus F1 (n = 17) and F5 CYP51s (n = 3), R. microsporus F1 and F5 CYP51s (n = 13 for both LDMs) and M. circinelloides F1 and F5 CYP51s (n = 18 for both LDMs) were aligned against S. cerevisiae CYP51 using T-coffee (Expresso)61. Residues within 4 Å of voriconazole in the structure S. cerevisiae CYP51 (PDBID: 5HS143) are highlighted in green. Those highlighted in red correspond to resistance mutations in CYP51 F5. The V to A substitution is shown in blue. Helices from the voriconazole CYP51 complex are shown above the alignment in gray and the heme coordinating cysteine is shown in yellow. The final two residues of the S. cerevisiae sequence are not shown. MH, Membrane-associated helix; TMD, transmembrane domain.
