The observation that a synthetic peptide, in which (parts of) three earlier described receptor interaction sites are combined according to the three-dimensional model, can mimic the action of FSH, at 10(-7) M, shows that this model is useful to predict a conformational receptor-binding site in FSH and that combination of only a few amino acid residues from the alpha and beta chains of FSH in a small synthetic peptide is sufficient to transduce a signal upon binding to the receptor.

(20) Cardiac myxomas typically present as a triad of obstructive, embolic, and constitutional symptoms and thus mimic many more common systemic illnesses.

Example Sentences:
(1) Further analysis with two other synthetic peptides (212Cys to 222Glu and Cys X 221Ile to 236Glu) indicated that the dodecapeptide Ile-Glu-Phe-Gln-Lys-Asn-Asn-Arg-Leu-Leu-Glu mimicked either the whole or a major part of the neutralization epitope.
