82 . A method of imparting glycosaminoglycan binding activity to a biological polymer or enhancing the glycosaminoglycan binding activity of a biological polymer, comprising linking to the biological polymer a tropoelastin derivative comprising an amino acid sequence having at least 65% similarity to the amino acid sequence of SEQ ID NO: 12 wherein the tropoelastin derivative binds glycosaminoglycan.
83 . A method as in claim 82 wherein the tropoelastin derivative consists of an amino acid sequence having at least 65% similarity to the amino acid sequence of SEQ ID NO: 14 or a part of SEQ ID NO: 14, and wherein the tropoelastin derivative binds glycosaminoglycan.
84 . A method as in claim 82 wherein the tropoelastin derivative consists of an amino acid sequence of SEQ ID NO: 14 or a part of SEQ ID NO: 14, which binds glycosaminoglycan.
85 . A method as in claim 82 wherein the tropoelastin derivative comprises the amino acid sequence from position 10 to position 200 of SEQ ID NO: 9.
86 . A method as in claim 82 wherein the tropoelastin derivative comprises the amino acid sequence of SEQ ID NO: 12.
87 . A method as in claim 82 wherein the tropoelastin derivative comprises the amino acid sequence from position 1 to 33 of SEQ ID NO: 12.
88 . A method of reducing glycosaminoglycan binding activity of a biological polymer which comprises a tropoelastin derivative having an amino acid sequence having at least 65% similarity to the amino acid sequence of SEQ ID NO: 12, comprising deleting the tropoelastin derivative from the biological polymer.
89 . A method as in claim 88 wherein the tropoelastin derivative has the amino acid sequence from position 1 to position 33 of SEQ ID NO: 12.
90 . A method as in claim 88 wherein the tropoelastin derivative has the amino acid sequence of SEQ ID NO: 12.
91 . A method as in claim 88 wherein the biological polymer is a tropoelastin molecule.
92 . A method as in claim 91 wherein the tropoelastin molecule comprises the amino acid sequence of SEQ ID NO: 2.
93 . A method as in claim 88 wherein the biological polymer is encoded by a nucleotide comprising the nucleotide sequence represented by SEQ ID NO: 1, and the tropoelastin derivative is deleted from the biological polymer by deleting from the nucleotide the nucleotide sequence from position 1678 to position 1776 of SEQ ID NO: 1 and expressing the nucleotide in a host cell.
