In mammalian spermiogenesis, haploid round spermatids undergo dramatic biochemical and morphological changes and transform into motile mature spermatozoa. A majority of the histones are replaced by transition proteins ...

Protein ageing is often mediated by the formation of succinimide intermediates. These short-lived intermediates derive from asparaginyl deamidation and aspartyl dehydration and are rapidly converted into beta-aspartyl or ...
