FIG. 2.

Restriction map of the insert in pTEX5159. The top line shows the scale. The shaded boxes represent contigs A to D. Below the boxes, the horizontal line represents the insert, the short vertical lines above the horizontal line represent the EcoRI sites, and the vertical lines below show the HindIII sites. The EcoRI fragments were designated r1 to r10, with r1 being the largest in size and r10 the smallest, while the HindIII fragments were designated h1 to h15. Fragment h2A had the same mobility in agarose gel electrophoresis as h2B; the same was true of h3A and h3B.
