Sirtuins are NAD (+)-dependent enzymes that deacetylate a variety of cellular proteins and in some cases catalyze protein ADP-ribosyl transfer. The catalytic mechanism of deacetylation is proposed to involve an ADPR-peptidylimidate, whereas the mechanism of ADP-ribosyl transfer to proteins is

Sirtuins are protein-modifying enzymes distributed throughout all forms of life. These enzymes bind NAD(+), a universal metabolite, and react it with acetyllysine residues to effect deacetylation of protein side chains. This NAD(+)-dependent deacetylation reaction has been observed for sirtuin enzymes

We have recently demonstrated that neutrophils oxidize nearly all of the amino acids commonly found in plasma to a corresponding family of aldehydes in high yield. The reaction is mediated by hypochlorous acid (HOCl), the major oxidant generated by the

We have previously shown that incubation of the model protein glucose-6-phosphate dehydrogenase (Glu-6-PDH) from the bacterium Leuconostoc mesenteroides with 4-hydroxy-2-nonenal (HNE), a major product of lipid peroxidation, results in the formation of cross-linked protein. HNE-modified protein is resistant to proteolytic
