Protein plasticity: a single amino acid substitution in the Saccharomyces cerevisiae oxidosqualene-lanosterol cyclase generates protosta-13(17),24-dien-3beta-ol, a rearrangement product.

Abstract excerpt

To provide insights into the structure-function relationships of oxidosqualene-lanosterol cyclase (ERG7) from Saccharomyces cerevisiae, the Phe699 was exchanged against hydrophilic polar uncharged residues Ser, Thr, Cys, Gln, and Tyr to characterize its product profile and functional role in ERG7...
