SSBs have multiple roles in binding and sequestering ssDNA, detecting DNA damage, stimulating strand-exchange proteins and helicases, and mediation of protein鈥損rotein interactions. Recently two additional human SSBs have been identified that are more closely related to bacterial and archaeal SSBs. ...
The single-stranded DNA of the lagging strand created by the action of the helicase is covered by tightly binding single-stranded DNA-binding proteins. In E. coli, this protein is a tetramer known as single-stranded-binding (SSB) protein, which the ssDNA winds itself around, while in T4 an...
百度试题 题目单链DNA 结合蛋白 (single-strand binding protein ,SSB) 相关知识点: 试题来源: 解析 是一类特异性和单链区 DNA 结合的蛋白质。它的功能在于稳定 DNA 解开的单链,阻止复性和保护单链部分不被核酸酶降解。反馈 收藏
解析 Single-strand()binding()protein()的中文名称是单链结合蛋白(()SSB()蛋白),又称()D()NA()结合蛋白,以四聚体形式存在于复制叉处,它能结合在单链()DNA()上,保证被解链酶解开的单链在复制完成前能保持单链结构,也可保护单链部分不被核酸酶降解,待单链复制完成后才离开,重新进入循环。()...
