Y141A the mutant enzyme is still active and converted the aliphatic (valeronitrile) and the aromatic substrate (2-phenylpropionitrile) with similar relative activities as the wild-type enzyme Pseudomonas fluorescens
Y141W the mutant enzyme converts valeronitrile with a much higher relative activity than 2-phenylpropionitrile Pseudomonas fluorescens

additional information the enzyme shows preference for unsaturated aliphatic substrates containing 5-6 carbon atoms. Increased reaction rates are also found for aliphatic nitriles carrying electron withdrawing substituents (e.g. chloro- or hydroxy-groups) close to the nitrile group. Aliphatic dinitriles are attacked only at one of the nitrile groups and with most of the tested dinitriles the monocarboxylates are detected as major products. Substrates converted with 1% less compared to the activity with 3-hexenedinitrile: 2-methylbutyronitrile, decanedinitrile, octanedinitrile, cis,trans-crotononitrile, popionitrile, isovaleronitrile, lactonitrile, butyronitrile, Pseudomonas fluorescens ?
