Summary of key observations (A) FxxA motif sequence conservation of Rad51 oligomerisation sequences and BRC repeats. (B) Highlight of SAR identified for the tetrapeptide. The differences in ΔG for different peptide variants relative to FHTA are shown in the bar chart with colouring matching with the structural overlay below. (C) Overlay of tetrapeptide structures, with wild‐type FHTA peptide across the figure for reference and truncated segments of mutated residues shown in each panel. Purple carbon is WHTA, light blue is FATA, yellow is FHPA, cyan is FHTG and grey carbon is FHTA. Note the C‐terminal amide changes position in FHTG without the anchoring methyl group.
