The resulting substrate mimetics act as efficient acyldonorcomponents and show the typical behavior of substrate mimicry enabling irreversible reactions with originally nonspecific acyl moieties. Neither a workup of the substrate mimetic intermediate nor changes of the reaction conditions during the whole synthesis process are required.

日期:——
A biocatalytic route to the ‘post-synthesis’
formation of Asp/Glu-derived isopeptides is illustrated on the basis of the
Staphylococcus aureus V8 protease used as the biocatalyst, a new
type of substrate mimetics as the donor peptides, and several acceptor
peptides varying in length and sequence.
