  1. ; (, Current opinion in structural biology)
    DNA mismatch repair (MMR) requires coordinated sequential actions of multiple proteins during a window of time after the replication apparatus makes an error and before the newly synthesized DNA undergoes chromosome compaction and/or methylation of dGATC sites in some g-proteobacteria. In this review, we focus on the steps carried out by MutS and MutL homologs that initiate repair. We connect new structural data to early and recent single-molecule FRET and atomic force microscopy (AFM) studies to reveal insights into how signaling within the MMR cascade connects MutS homolog recognition of a mismatch to downstream repair. We present unified models of MMR initiation that account for the differences in the strand discrimination signals between methyl- and non-methyl- directed MMR.
