Abstract

ABSTRACT A protein containing a nucleotidyltransferase motif characteristic of poly(A) polymerases has been proposed to polyadenylate RNA in Streptomyces coelicolor (P. Bralley and G. H. Jones, Mol. Microbiol. 40: 1155-1164, 2001). We show that this protein lacks poly(A) polymerase activity and is instead a tRNA nucleotidyltransferase that repairs CCA ends of tRNAs. In contrast, a Streptomyces coelicolor polynucleotide phosphorylase homologue that exhibits polyadenylation activity may account for the poly(A) tails found in this organism.
