  An objective of the present invention is to provide methods of synthesizing peptides containing structurally diverse amino acids using cell-free translation systems, which can accomplish excellent translational efficiency as compared to conventional techniques (the conventional techniques being methods which involve preparing aminoacyl-tRNAs which do not have protecting groups outside the translation systems without using ARS, and then adding the prepared aminoacyl-tRNAs into translation systems). In the present invention, it was found that amino acid-containing peptides can be synthesized efficiently by protecting an amino acid linked to tRNA with an appropriate protecting group, and then performing the step of deprotecting the protecting group of the amino acid linked to tRNA and the step of peptide translation from a template nucleic acid in a cell-free translation system in parallel.

  本发明的一个目标是提供使用无细胞翻译系统合成含有结构多样的氨基酸的肽的方法，这些方法可以实现与传统技术相比出色的翻译效率（传统技术是指涉及在翻译系统外部准备没有保护基的氨酰-tRNA而不使用ARS的方法，然后将准备好的氨酰-tRNA添加到翻译系统中）。在本发明中，发现通过用适当的保护基保护与tRNA连接的氨基酸，然后并行进行去保护氨基酸与tRNA连接的保护基的步骤和从模板核酸进行肽翻译的步骤，可以高效地合成含有氨基酸的肽。

  This invention relates to a collagen polypeptide comprising a tripeptide motif having the formula (ProYaaGly) n , where Yaa is an O-methylated amino acid residue and “n” is the number of motif repeats. Preferred O-methylated amino acid residues at the Yaa position include (2S,4R)-4-methoxyproline. Other suitable amino acid residues at that position include O-mono or O-di-halogenated methylproline. Also, disclosed is a method of making a synthetic or a semi-synthetic collagen polypeptide molecule having increased stability relative to natural collagen. The strengthened collagen molecules are suitable for use in biomaterials for the medical field or in leather-related products prepared by the tanning industry.

  本发明涉及一种胶原蛋白多肽，其包含具有公式（ProYaaGly）n的三肽基序，其中Yaa是O-甲基化的氨基酸残基，“n”是基序重复的次数。在Yaa位置的首选O-甲基化氨基酸残基包括（2S，4R）-4-甲氧基脯氨酸。该位置上的其他适当氨基酸残基包括O-单或O-双卤代甲基脯氨酸。此外，还揭示了一种制备具有相对于天然胶原蛋白增强稳定性的合成或半合成胶原蛋白分子的方法。强化的胶原分子适用于医学领域的生物材料或由制革工业制备的皮革相关产品。
