✦ Synopsis

Lipases and proteases from different sources were screened for their ability to catalyze the transesterification of glucose and activated N-blocked phen fs lalanine. A commercial 8 rotease from Bacillus licheniformis was found to be most e ective for this purpose.

n a basis of "C-NMR analysis, .glucose was acylated at the C-6 position. The enzyme showed a broad substrate specificity toward various monosaccharides.
