In addition, in the present application, peptides in which amino acids in a peptide form a crosslinked structure, those in which a cyclic structure is formed by lactam ring formation or macrocyclization reaction, and those having a ...
WebSpecifically, many cyclic peptides such as cyclotides are naturally produced in plants and in future modified ‘designer’ cyclic peptides might be produced in such plant biofactories by the inclusion of the appropriate precursor genes. WebFeb 2, 2024 · The primary cyclic peptide hit from the screen initially showed a weak affinity for the p110α-RBD (Kd about 360 µM). However, two rounds of amino acid substitution led to cyclo-CRVLIR, with an improved affinity for p110α-RBD in the low µM (Kd 3 µM). We show that cyclo-CRVLIR binds selectively to the p110α-RBD but not to KRAS or the ...
