Figure 2.
Fig. 2. Lasso domain with structural Zn2+. The coordination
of Zn2+ is shown as present in hTK1. In Uu-TK, the coordinating
amino acids are C153, C156, C191, and H194. The lasso is shown
in orange for hTK1. In Uu-TK, this loop is slightly longer
(shown in green). Additionally, the hydrogen bonding from the
conserved Arg-Tyr couple is shown.
