Nameprotein-coding palindromic elements
DescriptionTwo different classes are known, so far, of mobile palindromic elements that insert in-frame into genes of certain obligate intracellular bacteria and code for an amino acid insert in the host protein. In contrast to inteins, the insert is relatively small and does not get spliced out. Rather, it appears the affected protein continues to function because the location of the insert is not destructive to correct protein folding. The two classes described so far are designated RPE, discovered in Rickettsia, and WPE, discovered in Wolbachia.
