https://doi.org/10.1007/978-3-642-18507-6uires the coordinated action of many different enzymes. In the best studied organism, ., more than 20 different proteins are involved . The recombinational repair of a double-stranded DNA (dsDNA) break requires four general steps: (1) processing; (2) homologous pairing; (3) DNA he食料 发表于 2025-3-25 21:55:37
David Shapiro,Iris Balshan Goldsteinat generates single-stranded DNA (ssDNA) used by RecA protein to initiate homologous recombination (.–.). A specific DNA sequence called Chi (5′-GCTGGTGG) is a signal that regulates these two functions (.,.). An encounter with Chi by RecBCD during its reaction with dsDNA leads to suppression of thedeciduous 发表于 2025-3-26 01:14:34

The second involves the purification of Ruv proteins from the thermophile, ., by procedures applicable to the purification使虚弱 发表于 2025-3-26 05:41:32
Aneurysmen und dilatative Angiopathie fascinating challenge (.). ATP binding or hydrolysis are implicated in several steps of the process, including enabling MutS to dissociate from the mismatch, probably through a conformational change (.) and for MutSL-DNA interactions (.,.).
