The invention concerns novel coagulation factor VII variants, wherein the
Leu residue in position 305 or the Phe residue in position 374 of SEQ ID
NO 1 has been replaced by another amino acid residue which can be encoded
by nucleic acid constructs and, optionally, wherein at least one other
amino acid residue in the remaining positions in the protease domain has
been replaced by another amino acid residue which can be encoded by
nucleic acid constructs;
with the proviso that the variant is not FVII(Ala305).
The invention further concerns nucleic acids encoding the Factor VII
variants; vectors and cells comprising the nucleic acid; methods for
producing the variants; pharmaceutical compositions comprising a Factor
VII variant wherein the Leu residue in position 305 or the Phe residue in
position 374 of SEQ ID NO 1 has been replaced by another amino acid
residue which can be encoded by nucleic acid constructs and, optionally,
wherein at least one other amino acid residue in the remaining positions
in the protease domain has been replaced by another amino acid residue
which can be encoded by nucleic acid constructs; use of the variants for
producing a medicament for treatment or prophylaxis of bleeding disorders
or enhancement of the coagulation system; and methods of treatment.
