Scientists occupy captured atomic level snapshots showing how one key enzyme modifies a protein involved in turning genes on or off inside cells. Understanding this process-which is particularly primary when cells are first taking on specialized identities such as nerve cells,muscle, skin, or so on-helps interpret how complex organisms can arise from a finite number of genes. The research,published in Nature Chemical Biology, also identifies links between defects in this particular enzyme and certain cancers, or potentially pointing to new targets for anticancer drugs.
