Figure 1From: The iron-sulfur cluster assembly genes iscS and iscU of Entamoeba histolytica were acquired by horizontal gene transferOverview of the 5'-flanking region of E. histolytica iscU (A) and iscS (B) encoding genes. The three typical upstream regulatory elements are depicted as by Purdy et al [23]; the putative initiator element, double underlined; the `GAAC'-element, grey box; and the putative TATA element, boxed.Back to article page
