Structural development of the HIV-1 apex-directed PGT145-PGDM1400 antibody lineage by Rosemarie D. Mason, Baoshan Zhang, Nicholas C. Morano, Chen-Hsiang Shen, Krisha McKee, Ashley Heimann, Renguang Du, Alexandra F. Nazzari, Shelby Hodges, Tapan Kanai, Bob C. Lin, Mark K. Louder, Nicole A. Doria-Rose, Tongqing Zhou, Lawrence Shapiro, Mario Roederer, Peter D. Kwong, Jason Gorman

“…Despite similar breadth and potency, the two antibodies differ in their residue-level interactions with important apex features, including N160 glycans and apex cavity, with residue 100i of PGT145 (sulfated tyrosine) penetrating ∼7 Å farther than residue 100i of PGDM1400 (aspartic acid). …”

An Assay System for Plate-based Detection of Endogenous Peptide:N-glycanase/NGLY1 Activity Using A Fluorescence-based Probe by Hiroto Hirayama, Tadashi Suzuki

“…Cytosolic peptide: N-glycanase (PNGase/NGLY1 in mammals), an amidase classified under EC:3.5.1.52, is a highly conserved enzyme across eukaryotes that catalyzes the removal of N-glycans from glycoproteins, converting N-glycosylated asparagine residues into aspartic acid. …”

Neuraminidase-mediated enhancement of Streptococcus pneumoniae colonization is associated with altered mucus characteristics and distribution by Matthew T. Montgomery, Mila Ortigoza, Cynthia Loomis, Jeffrey N. Weiser

“…ABSTRACT Upon entry into the upper respiratory tract (URT), Streptococcus pneumoniae (Spn) upregulates neuraminidases (NA) that cleave sialic acid (SA) from host glycans. Because sialylation is thought to contribute to the physical properties that determine mucus function, we posited that Spn directly alters host mucus through NA activity. …”

Transforming monosaccharides: Recent advances in rare sugar production and future exploration by Shin-ichi Nakakita, Jun Hirabayashi

“…In this scenario, monosaccharides, which constitute various kinds of glycans in nature, are assumed to have been generated by formose reactions on the prebiotic Earth (chemical evolution era). …”

Sporothrix brasiliensis Gp70 is a cell wall protein required for adhesion, proper interaction with innate immune cells, and virulence by Leonardo Padró-Villegas, Manuela Gómez-Gaviria, Iván Martínez-Duncker, Luz A. López-Ramírez, José A. Martínez-Álvarez, Gustavo A. Niño-Vega, Héctor M. Mora-Montes

“…This was accompanied by a reduction in protein content and N-linked glycans. Mutant strains with high GP70-silencing levels showed minimal levels of 3-carboxy-cis,cis-muconate cyclase activity, this glycoprotein's predicted enzyme function, and decreased ability to bind laminin and fibronectin. …”

Faecalibacterium prausnitzii regulates carbohydrate metabolic functions of the gut microbiome in C57BL/6 mice by Peiling Geng, Ni Zhao, Yufan Zhou, Reuben S. Harris, Yong Ge

“…Further analysis uncovered a functional network wherein UT1 reduced the abundance of mucin-degrading CAZymes and microbes, which correlated with a concomitant reduction of fecal mucin glycans. Collectively, our results reveal a crucial role of UT1 in facilitating the carbohydrate metabolism of the gut microbiome and expand our understanding of the genetic and phenotypic diversity of F. prausnitzii.…”
