Figure 5

Comparison of the C-terminal FGFRL1 sequences from humans, lancelet and sea urchin. Histidine residues are highlighted in bold. Atomic absorption spectroscopy showed that the human protein bound 2.6 mole zinc/mole protein, while the sea urchin protein bound 1.7 mole zinc/mole protein. The standard deviation from three different measurements was < 2%. The zinc content of the lancelet protein was not determined (n.d.), but this sequence was included for reasons of comparison.
