Reversible lysine acetylation is one of the most important protein posttranslational modifications that plays essential roles in both prokaryotes and eukaryotes . However , only a few lysine deacetylases ( KDACs ) have been identified in prokaryotes , perhaps in part due to their limited sequence homology . Herein , we... | After proteins have been made , they can be modified in several ways . For example , chemical tags called acetyl groups may be added to ( and later removed from ) the protein to regulate cell activities such as aging and metabolism . Enzymes are proteins that help catalyze the reactions that add or remove the acetyl ta... | [

CLC secondary active transporters exchange Cl- for H+ . Crystal structures have suggested that the conformational change from occluded to outward-facing states is unusually simple , involving only the rotation of a conserved glutamate ( Gluex ) upon its protonation .

For example , the CLC family of transporters move two chloride ions in one direction at the same time as moving one hydrogen ion in the opposite direction . To be able to move these ions in opposite directions , transporters ha... | [
