Mismatch in heteroduplex DNA with nick 3' to mismatch bound by MutSalpha
[Homo sapiens]
| MutS searches binds to DNA in the nucleotide-free or ADP-bound state. The binding of MutS to DNA induces bending of both homo- and heteroduplex DNA. When MutS encounters the mismatch, a bend is turned into a sharp kink. This triggers a conformational change in the protein and the exchange of ADP to ATP. |
Mismatch in heteroduplex DNA with nick 3' to mismatch bound by MutSalpha is part of following pathways: This DNA state is a resulting state in the following reactions:
| Reaction | Previous state | Following state |
| MutSalpha binds mismatch in heteroduplex DNA with nick 3' to mismatch in Homo sapiens | Heteroduplex DNA with nick 3' to mismatch in Homo sapiens | Mismatch in heteroduplex DNA with nick 3' to mismatch bound by MutSalpha in Homo sapiens |
This DNA state is a previous state in the following reactions:
