Scientists Solve Long-Standing Plant Biochemistry Mystery
ScienceDaily (Sep. 19, 2011) — Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory and collaborators at the Karolinska Institute in Sweden have discovered how an enzyme "knows" where to insert a double bond when desaturating plant fatty acids. Understanding the mechanism -- which relies on a single amino acid far from the enzyme's active site -- solves a 40-year mystery of how these enzymes exert such location-specific control.
