Role of sirtuins in lifespan regulation is linked to methylation of nicotinamide
Nature chemical biology(2013)
Abstract
Nematodes define a new role for sirtuins in lifespan extension, in which the sirtuin product nicotinamide is converted to a substrate for aldehyde oxidase; turnover of this enzyme generates hydrogen peroxide, causing upregulation of defense mechanisms that promote longevity.
