Role of glycans on the SARS-CoV-2 spike protein in human receptor interaction

A team of investigators, led by Dr. Benjamin F. Mann, from Merck, USA have published a new study on the preprint server bioRxiv*. They have used a biochemical approach to control the glycosylation profile of the S protein receptor-binding domain (RBD) and to analyze the effect of different glycosylation patterns on receptor binding.

SARS-CoV-2 interacts with sialic acid cell surface glycans

In a paper recently uploaded to the journal Frontiers in Chemistry by Li et al. (July 22nd, 2021) the interaction between the SARS-CoV-2 spike protein and N-acetylneuraminic acid (NANA), the most commonly found sialic acid in humans, is investigated, finding that the molecule may act as a secondary or supplementary receptor to the virus.

Research shows how loss of de-N-glycosylation enzyme causes detrimental effects

Peptide: N-glycanase (NGLY1) is an evolutionarily conserved enzyme for removing N-linked glycans (N-glycans) from glycoproteins and is involved in proteostasis of N-glycoproteins in the cytosol. In 2012, a rare genetic disorder called NGLY1 deficiency was discovered by an exome analysis.

Study explores lectins from plants, fungi, algae and cyanobacteria as pan-coronavirus inhibitors

In a recently published article scientists have provided a detailed description of the utility of mannose-specific lectins in preventing coronavirus infections. They have specifically explained how mannose-specific lectins derived from plants, algae, fungi, and bacteria selectively bind N-glycans present on the surface of viral spike protein and how such interactions can be medically utilized to control coronavirus transmission.

SARS-CoV-2 causes ER-stress-activated unfolded protein response leading to cell death

A new study describes the varying ways in which the virus co-opts the machinery of the host cell following infection to evade or modulate the host immune response, alter the pattern of translation of viral proteins, and the release of new viral particles.
