Determine whether substituting key amino acid residues in yeast tubulin with mammalian equivalents can confer Taxol binding and microtubule stabilization.
Identified five candidate amino acid differences between Saccharomyces cerevisiae and mammalian brain tubulin using binding and structural modeling data.
Engineered yeast tubulin by mutating the five identified residues to match mammalian sequences.
Assayed the engineered yeast tubulin for Taxol binding and microtubule assembly activity.
Targeted mutation of five amino acid residues in yeast tubulin restored Taxol-related microtubule-stabilizing activity comparable to mammalian tubulin.
The modified yeast tubulin system provides an in vitro platform to analyze structural interactions with Taxol, epothilones, and related antimitotic agents.
