l-methionine related l-amino acids by acylase cleavage of their corresponding
摘要:
Acylase I from Aspergillus oryzae is an even more useful enzyme than suggested so far. Besides standard amino acids such as L-Met, L-VaI 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-acety-DL-amino acids.

The feeding study using L-[1-13C]methionine revealed that labelled carbons were incorporated into C-1, 4′, and 4″ of purified mugineicacid and 2′-deoxymugineicacid from their 13C-NMR spectra.
