Figure 1. Crystal structure of AGT from Anabaena sp. (A) Stereo
ribbon diagram of Anabena sp. AGT color-coded from N-terminus
(blue) to C-terminus (red), showing the domain organization and
location of the putative active site (PLP molecule shown in
ball-and-stick representation). Helices H1-H15 and  -strands
( 1-
12),
as well as -sheets
A, B, and C are indicated. (B) Diagram showing the secondary
structure elements in Anabaena sp. AGT superimposed on its
primary sequence. The -sheet
designations are indicated by a red A, B, and C. Above each -strand,
-bulges
and  -turns
are indicated. -hairpins
are depicted as red loops. Disordered regions are depicted by a
dashed line, with the corresponding sequence in brackets.
