Recently, a study demonstrated an engineered banana lectin (BanLec, Lens culinaris) that importantly decreased mitogenicity by replacing histidine 84 with a threonine (H84T-BanLec) and introduction of a single amino acid substitution [1]. H84T-Banlec demonstrated potent broad-spectrum against viruses high-mannose N-glycans (particularly oligomannose-type glycans and GlcNAC at the non-reducing end terminus and artificial mutants at N-/O-linked glycosylation with most potent and broad antiviral activity against the epidemic variants B.1.1.7, B.1.351, and P.1 [2]), such as severe-acute-respiratory-syndrome coronavirus (SARS-CoV-2 (COVID-19)) and middle-east-respiratory-syndrome coronavirus (MERS-CoV) in vitro and in vivo, in addition to Ebola virus, human immunodeficiency viruses 1 and 2, hepatitis C virus, and influenza viruses A and B, via highly-glycosylated-viral proteins for blocking the cell attachment, cell entry, fusion of membrane, and coronavirus replication [1,3-5]. At 1 mg/mL, lentil lectin revealed no cytotoxic activity and weak hemagglutination [2]. In mouse model, with single injection, no weight loss was identified [2]. Lentil lectin could block inhibit the binding of the human anti-converting-enzyme-2 (ACE 2) receptors to SARS-CoV-2 (COVID-19)-S-trimer protein [2,6]
