Figure 1. Three-dimensional ribbon structure of APS reductase from A. fulgidus.

Figure 1

The beta-subunit segments are colored red (ferredoxin segment), blue (3 antiparallel beta-sheets segment), and green (tail segment); the alpha-subunit domains are colored light blue and orange (FAD-binding domain I and II), pink (capping domain), and grey (helical domain). The [4Fe-4S] clusters, FAD and substrate APS are shown as ball-and-stick representations; tryptophan Trp-B48 of AprB is highlighted by violet color. Ribbon structure is shown from (A) top view, (B) bottom view (substrate channel), (C) front view, and (D) back view.
