Phosphate lock loop

WebThis conformational change upon binding at a PAM motif can help to stabilize the phosphate lock loop (Lys1107-Ser1109 in Cas9) which likely licenses sgRNA for invasion into duplex DNA and subsequent R-loop propagation (Cofsky et al., 2024). WebNov 30, 2024 · Abundant and essential motifs, such as phosphate-binding loops (P-loops), are presumed to be the seeds of modern enzymes. The Walker-A P-loop is absolutely essential in modern NTPase enzymes, in mediating binding, and transfer of the terminal phosphate groups of NTPs.
