disulfide bridge 中文意思是什麼
disulfide bridge
解釋
二硫化橋鍵-
Disulfide bridge in proteins, a covalent bond formed between the sulfhydryl ( - sh ) groups of different cysteine molecules. such bridges are important in stabilizing the tertiary structure of peptides and proteins
二硫橋：在蛋白質中兩個半胱氨酸殘基的兩個巰基之間形成的共價鍵。這樣的結構對于維持多肽和蛋白質三級結構的穩定有重要的作用。 -

Thioredoxins, an ubiquitous small proteins with a redox active disulfide bridge in its conserved motif - cp ( g ) pc -, are universally distributed in eucaryote and procaryote and have a molecular mass of approximately 12kda. by its disulfide / dithiol interchange reaction, this protein can transmit the regulatory signals to seleted targets ( enzymes, transcription factors etc ) and plays an important role in many plant physiological processes that includes photosynthesis, dna synthesis, transcription, protein disulfide reduction, protein repair, filamentous phage assembly, cell apoptosis and seeds germinating and so on
該蛋白質中含有保守的- cp （ g ） pc -氨基酸活性基序，該基序中的兩個半胱氨酸殘基可通過巰基二硫鍵的轉換實現其氧化還原狀態的變化和電子氫的傳遞，對細胞中與氧化還原相關的多種生理過程的調節起重要作用。通過同許多酶類、蛋白類、細胞內活性因子相藕連， trx能對光合作用、 dna復制、基因轉錄、細胞凋亡和生長、噬菌體組裝、蛋白質的還原和修復信號傳導等生理過程產生影響和調節。
