Studies and sequences of Escherichia coli 4.5 S RNA
B. E. Griffin
4.5 S RNA, a biologically stable species with electrophoretic properties
intermediate between 5 S and transfer RNAs, has been isolated from
Escherichia coli and characterized. No function has yet been found for
this molecule. Its primary structure and behavior suggests an unusually
stable and possibly unique secondary structure. Even from single species
of E. coli, there is some sequence heterogeneity within the molecule. The
sequence of a major species from MRE 600 is: (see article). Methods for
getting sequence overlaps on this highly structured RNA are described, and
a possible functional role for 4.5 S RNA is discussed.
