The novel coronavirus, SARS-CoV-2, enters cells through binding of the receptor binding domain (RBD) on its spike protein to angiotensin converting enzyme 2 (ACE2). Spike-binding Peptide 1 (SBP1) was derived from the ACE2 a1 helix and binds to SARS-Cov-2 RBD with low nanomolar affinity (Kd = 47 nM).
