Figure 1.
Figure 1. Crystal structure of AtCKX7. (A) Ribbon diagram of
AtCKX7. The FAD-binding and the substrate-binding domains are
shown in cyan and red, respectively. The FAD molecule is
represented as a stick model in yellow. (B) Covalent bond
between His96 and the isoalloxazine ring of the FAD molecule.
The FAD is shown in yellow and the His residue is colored by
atom types (carbon: green; oxygen: red; nitrogen: blue). The
2F[obs] - F[calc] map is contoured at 1.5  .

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.
