Figure 1.
Figure 1. (A) Ribbon diagram of the TM0293 monomer with its three domains labeled; -helices are in red and -strands are in cyan. The proposed catalytic cysteine, Cys255, is represented in ball-and-stick, with the sulfur in yellow; a prominent difference density around the Cys sulfhydryl group suggests it may be in an oxidized form (density not shown). The NADPH and hinge regions are indicated by arrows, and the N and C termini are labeled. (B) The crystallographic TM0293 tetramer; each monomer is colored separately. (C) Diagram showing the secondary structure elements of TM0293 superimposed on its primary sequence. Helices are labeled H1 to H19. Strands are labeled according to their respective -sheets: A (the oligomerization domain III), B (the cofactor binding domain I), C (the catalytic binding domain II) and D (the hinge). The locations of the hairpin loops, as well as the location of turns and turns, are also depicted in the diagram.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time.
