CsrA_protein
Carbon storage regulator A (CsrA) is an RNA binding protein. The CsrA homologs are found in most bacterial species, in the pseudomonads they are called repressor of secondary metabolites (RsmA and RsmE).[2] The CsrA proteins generally bind to the Shine-Dalgarno sequence of messenger RNAs and either inhibit translation or facilitate mRNA decay.[3]
CsrA has a regulatory effect on glycogen biosynthesis and catabolism, glycolysis,[3] biofilm formation[4] and quorum sensing.[5]
