What a bind! The CYP101B1 enzyme from the bacteria N. aromaticivorans has been engineered to better bind and oxidise hydrophobic aromaticsubstrates. His85 was identified by sequence alignment as a potential active-site residue. The H85F variant improved activity and offered unusual selectivity options.

having allelopathic activity, has been accomplished employing an enyne metathesis for the construction of the C1-C8 segment and two-carbonelongation via a nitrile oxide-alkene [3+2] cycloaddition as the key steps. enyne metathesis - total synthesis - ionones - nitrile oxide - cycloaddition
