The COVID-19 pandemic caused by SARS-CoV-2 infection has led to socio-economic shutdowns and the loss of over 5 million lives worldwide. There is a need for the identification of therapeutic targets to treat COVID-19. SARS-CoV-2 spike is a target of interest for the development of therapeutic targets. We developed a robust SARS-CoV-2 S spike expression and purification protocol from insect cells and studied four recombinant SARS-CoV-2 spike protein constructs based on the original SARS-CoV-2 sequence using a baculovirus expression system: a spike protein receptor-binding domain that includes the SD1 domain (RBD) coupled to a fluorescent tag (S-RBD-eGFP), spike ectodomain coupled …

Unlike the α-helical and β-sheet antimicrobial peptides (AMPs), our knowledge on amino acid-rich AMPs is limited. This article conducts a systematic study of rich AMPs (>25%) from different life kingdoms based on the Antimicrobial Peptide Database (APD) using the program R. Of 3425 peptides, 724 rich AMPs were identified. Rich AMPs are more common in animals and bacteria than in plants. In different animal classes, a unique set of rich AMPs is deployed. While histidine, proline, and arginine-rich AMPs are abundant in mammals, alanine, glycine, and leucine-rich AMPs are common in amphibians. Ten amino acids (Ala, Cys, Gly, His, …

The creation of several prestin knockout and knockin mouse lines has demonstrated the importance of the intrinsic outer hair cell membrane protein prestin to mammalian hearing. However, the structure of prestin remains largely unknown, with even its major features in dispute. Several studies have suggested that prestin forms homo-oligomers that may be stabilized by disulfide bonds. Our phylogenetic analysis of prestin sequences across chordate classes suggested that the cysteinyl residues could be divided into three groups, depending on the extent of their conservation between prestin orthologs and paralogs or homologs. An alanine scan functional analysis was performed of all nine …
