Substrate for the assay of collagenase activity. Cleavage of Dnp-PQGIAGQR yields Dnp-PQG, M-1335.
Dnp-Pro-Gln-Gly-Ile-Ala-Gly-Gln-D-Arg is a synthetic peptide that is used as a research tool, an activator, and an inhibitor. This peptide is not expected to have any adverse effects on the environment or on animal or human health. It can be used in antibody production and has been shown to inhibit the activity of ion channels. Dnp-Pro-Gln-Gly-Ile-Ala-Gly-Gln-D-Arg binds to receptors and ligands, which may be involved in protein interactions.
很多蛋白在细胞中非常容易被降解,或被标记,进而被选择性地破坏。但含有部分D型氨基酸的多肽则显示了很强的抵抗蛋白酶降解能力。
