Circular representation of the S. mutans, strain UA159 genome. The outer two circles show the position of the probable ORFs on the complementary DNA strands. The ORFs have been color coded by functional category. The remaining circles are, proceeding inward: the location of the mobile genetic elements, the ABC transporters involved in the sugar metabolism, the PTS transporters and PTS Enzyme I, the position of the ribosomal (black) and tRNA (green), the %G+C of the sequence, and the %G+C deviation by strand.
