1.15.1.1 additional information equilibrium binding of Escherichia coli MnSOD to poly(U), poly(A), poly(C), poly(dU) and double-stranded (ds) DNA, overview. The polynucleotides bind to MnSOD in the following affinity hierarchy, poly(dU) N poly(U) N dsDNA N poly(A) N poly(C). The differences in the hierarchy are not large in magnitude as the poly(dU) bound with less than a 100fold higher affinity than poly(C). For each polynucleotide, Kobs decreases only slightly with increasing [K+], surprising for a relatively non-specific nucleic acid protein. There is either only one binding site shared by these polynucleotides or the larger site size occluded by poly(C) overlaps that of poly(U) and poly(A), but extends further on the protein Escherichia coli ?

1.15.1.1 physiological function the bacterial manganese superoxide dismutase (MnSOD) localizes to the chromosomal portion of the cell and impart protection from ionizing radiation to DNA. MnSOD can bind to RNA leads to the possibility that MnSOD may confer protection to RNA, as well Escherichia coli
