Application of KIE and thia approaches in the mechanistic study of a plant stearoyl-ACP Δ9 desaturase
Abstract
The mechanism of the castor stearoyl-ACP Δ9 desaturase has been investigated; it has been shown that C–H cleavage at carbons 9 and 10 is not sensitive to deuterium substitution and oxo-trapping experiments using thia analogues revealed that sulfoxidation occurs when the substrate bears sulfur at the 9 and 10 positions.
