l-methionine related l-amino acids by acylase cleavage of their corresponding N-acetyl-dl-derivatives

Abstract Acylase I from Aspergillus oryzae is an even more useful enzyme than suggested so far. Besides standard amino acids such as l -Met, l -Val and l -Phe, a number of additional sulfur- and selenium-containing amino acids can be obtained at useful reaction rates and in very high enantiomeric purity by kinetic resolution of the respective N- acetyl- dl -amino acids.
