WebNov 15, 2024 · Although PAM recognition is essential for cleavage, it is unknown whether and how PAM binding activates Cas9 for DNA cleavage at spatially distant sites. Here, we find evidence of a PAM-induced allosteric mechanism revealed by microsecond molecular dynamics simulations. WebNov 2, 2024 · A survey of 16 uncharacterized Cas12a enzymes revealed differences in both PAM recognition and cut site repair mechanism ( Zetsche et al., 2024 ), suggesting that it should be possible to engineer a range of activities into members of the Cas12a family.
