FIG. 5. Sequence alignment of the PlGF and VEGF
receptor-binding domain. Secondary structure elements are
depicted at the top with dark gray arrows referring to -strands
and light gray boxes to -helices. Numbers at
top refer to human PlGF and numbers at bottom to human VEGF
sequence. green, strictly conserved in all shown sequences;
yellow, conserved in VEGF or PlGF only; orange, conserved among
PlGF and among VEGF as different residues; bold font, monomer 1
receptor binding interface; bold font and underlined, monomer 2
receptor binding interface; boxed residues, core of receptor
interface; italics, residues involved in dimer interface.
