Evidence for non-enzymatic glycosylation in Escherichia coli.


Non-enzymatic glycosylation (glycation) is a chain of chemical reactions affecting free amino groups in proteins of long-living eukaryotes. It proceeds in several steps leading to the consecutive formation of Schiff bases, Amadori products and advanced glycation end-products (AGEs). To our knowledge, this process has not been observed in prokaryotes so far… (More)
