Abstract
At present, the non redundant contig sequences of E.coli which covers about 70% of the whole chromosome are constructed. We predicted ORF's (Open Reading Frames) from 2, 554, 518 bp contig sequences on the basis of Shine-Dalgarno (ribosome binding) sequence. All ORF's were classified according to the structural similarities. Through examining the homology of ORF's in each group in detail, some structural units were revealed.
