Estimating the term…
The present application provides a preparation method for biosynthesis of a human body structural material. A polypeptide has the amino acid sequence of SEQ ID NO. 4, 5 or 6. Recombinant type-VII humanized collagen prepared in the present application has high activity of promoting cell proliferation and does not produce an immune response when applied to a human body, and the preparation method therefor is novel and can obtain the recombinant type-VII humanized collagen on a large scale, and is widely applied in the preparation of human body structural materials.
A polypeptide which consists of an amino acid sequence of (repeating unit)n or is 90%-99% identical to the amino acid sequence of (repeating unit)», wherein the repeating unit consists of the amino acid sequence of SEQ ID NO:
