别 名: SD sequence

词 性: 名词

中文解释:

亦称核糖体识别位点(ribosome recognition site),核糖体结合位点(ribosome binding site),核糖体结合序列(ribosome binding sequence)。是mRNA中5'端富含嘌呤的短核苷酸序列,一般位于mRNA的起始密码AUG的上游5～10个碱基处,并且同16S rRNA 3'端的序列互补,它是1974年由J.Shine 和 L.Dalgarno发现的,故名[SD序列(Shine-Dalgarno sequence)]。

英文解释:

In messenger RNA, a purine-rich region about 10 nucleotides on the 5' side of an initiator codon that pairs with the 3' end of 16S RNA in the 30S ribosomal subunit; helps to determine where translation is initiated on an mRNA molecule.
