项目摘要
Project Summary/Abstract
Protein-protein interactions (PPIs) are involved in a diverse array of critical biological processes,
including cell proliferation, growth, differentiation, and apoptosis. To date, there is no general way to
modulate collagen protein-protein interactions, and many fundamental aspects of biomolecular
recognition are still unknown. Specifically, numerous interactions between collagen triple helices and
proteins are not fully characterized or understood. We have recently shown that collagen aza-peptides
in which at least one alpha-carbon atom has been substituted with nitrogen, have additional interstrand
hydrogen bonds in their collagen triple helix, resulting in hyperstability and more efficient self-assembly.
As a result, even short collagen aza-peptides reliably self-assemble into thermostable triple helices,
making them a promising choice for novel triple helix mimics. With this project, we propose to use
minimal aza-peptides to create linear and cyclic collagen peptide triple helix mimics. Our specific aims
are as follows: 1) Synthesize and characterize hyperstable synthetic mimics of collagen peptides; 2)
Synthesize and characterize cyclic collagen peptide triple helix mimics (CCP-mimics); 3) Characterize
protein interactions our synthetic collagen peptides. Aza-peptides will be synthesized using solid-phase
peptide synthesis (SPPS) in order to introduce aza-amino acids into the collagen backbone at precise
locations and optimize thermodynamic stability of the linear and cyclic peptides. The modular nature of
our new collagen peptide systems will provide highly tunable platforms into which any biologically
relevant protein binding sequence can be integrated. Our collagen peptide mimics will serve as new
chemical tools for understanding the fundamental biology and biochemistry of the collagen-protein
interactome. The proposed studies could ultimately serve as the fundamental science leading to future
biomedical treatments for pathologies in which precisely modulating collagen-protein interactions could
significantly enhance patient outcome.
项目总结/摘要
蛋白质-蛋白质相互作用(PPI)涉及多种关键生物过程,
包括细胞增殖、生长、分化和凋亡。到目前为止,还没有一种通用的方法来
调节胶原蛋白-蛋白质相互作用,以及生物分子的许多基本方面,
识别仍然是未知的。具体地说,胶原蛋白三螺旋之间的许多相互作用,
蛋白质没有被完全表征或理解。我们最近发现胶原蛋白氮杂肽
其中至少一个α-碳原子被氮取代,具有额外链间
它们的胶原蛋白三螺旋中的氢键,导致超稳定性和更有效的自组装。
因此,即使是短的胶原氮杂肽也能可靠地自组装成热稳定的三螺旋,
使它们成为新型三螺旋模拟物的有希望的选择。在这个项目中,我们建议使用
最小的氮杂肽,以产生线性和环状胶原蛋白肽三螺旋模拟物。我们的具体目标
如下:1)合成和表征胶原蛋白肽的超稳定合成模拟物; 2)
合成和表征环状胶原蛋白肽三螺旋模拟物(CCP-模拟物); 3)表征
蛋白质相互作用我们的合成胶原肽。氮杂肽将使用固相合成
肽合成(SPPS),以便将氮杂氨基酸以精确的
位置和优化的线性和环状肽的热力学稳定性。的模块化性质
我们的新胶原蛋白肽系统将提供高度可调的平台,
可以整合相关蛋白结合序列。我们的胶原蛋白肽模拟物将作为新的
理解胶原蛋白的基本生物学和生物化学的化学工具
相互作用体拟议中的研究最终可能成为未来的基础科学。
用于病理的生物医学治疗,其中精确调节胶原蛋白-蛋白质相互作用可以
显著提高患者疗效。
