Abstract

Exhaustive identification of open reading frames in complete genome sequences is a difficult task. It is possible that important genes are missed. In our efforts to reanalyze the intergenic regions of Mycoplasma genitalium and Mycoplasma pneumoniae, we have newly identified a number of new open reading frames (ORFs) in both M. genitalium and M. pneumoniae. The most significant identification was that of a ribonuclease H enzyme in both species which until now has not been identified or assumed absent and interpreted as such. In this paper we discuss the biological importance of RNase H and its evolutionary implication. We also stress the usefulness of our method for identifying new ORFs by reanalyzing intergenic regions of existing ORFs in complete genome sequences.
