Recently, Ne-lysine acetylation was realized to be a prevalent bacterial post-translational modification (PTM), contrary to the historical notion that this was a rare occurrence. Acetylation can impact protein function in multiple ways, by modifying conformation, interactions, subcellular localization or activity. In bacteria, hundreds of proteins are known to be acetylated, including those involved essential processes such as DNA replication, nucleoid organization, translation, cell shape, central carbon metabolism, and even several virulence factors. Despite the growing recognition that numerous proteins are acetylated, the biological significance of the vast majority of these modifications in any bacteria remains largely unknown. Previously ...

Specific genes called heterochronic genes control the timing and sequence of developmental events during larval stages of C. elegans. Mutations in heterochronic genes can cause skipping or reiteration of cell fates associated with certain larval stages. lin-14 and lin-28 are two well-studied heterochronic genes. LIN-14 acts during the first larval stage (L1) and controls events of the L1 and L2 stages, LIN-28 acts during the L2 stage and controls its events.
