Peptides mimicking the flap of human renin: synthesis, conformation, and antibody recognition.
Four peptides related to human renin flap region have been synthesized. Two of them are ring closed through appropriately designed disulfide bridges. Structure analysis involving IR and NMR techniques and recognition by polyclonal human renin antibodies provides support for a beta-hairpin secondary structure of the cyclized peptides identical with that presented by the flap section in the speculative human renin model [Blundell, T., Sibanda, B. L., & Pearl, L. (1983) Nature (London) 304, 273-275; Sibanda, B. L., Blundell, T., Hobart, P. M., Fogliano, M., Bindra, J. S., Dominy, B. W., & Chirgwin, J. M. (1984) FEBS Lett. 174, 102-111].
