TranscriptomicsTranscriptional regulation of the sialic acid utilization gene cluster of Bifidobacterium breve UCC2003 by a GntR-type transcriptional repressor.
Members of the genus Bifidobacterium are typically found in the gastrointestinal tract (GIT) of humans and other mammals. Bifidobacterium breve strains are numerically prevalent among the gut microbiota of healthy, breast-fed infants. The metabolism of sialic acid, a ubiquitous monosaccharide in the...

ProteomicsPrecision Characterization of Site-specific O-Acetylated Sialic Acids on N-Glycoproteins
O-Acetylation is a common modification of sialic acid, playing a significant role in glycoprotein stability, immune response, and cell development. The lack of efficient methods for direct analysis of O-acetylated sialoglycopeptides (O-AcSGPs) made the majority of identified O-acetylated sialic acid...

ProteomicsA Linkage- Specific Sialic Acid Labeling Strategy Reveals Different Site-Specific Glycosylation Patterns in SARS-CoV-2 Spike Protein Produced in CHO and HEK Cell Substrates
The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus utilizes an extensively glycosylated spike protein that protrudes from the viral envelope to bind to angiotensin-converting enzyme-related carboxypeptidase (ACE2) as its primary receptor to mediate host-cell entry. Currently, the...

TranscriptomicsTranscription profiling of mouse tumors arising in wild-type or St6gal1 null littermates
Sialic acids on vertebrate cell surfaces mediate many biological roles. Altered expression of certain sialic acid types or their linkages can have prognostic significance in human cancer. A classic but unexplained example is enhanced α2-6-sialylation on N-glycans, resulting from over-expression of ...

TranscriptomicsMetabolism of sialic acid by Bifidobacterium breve UCC2003
Bifidobacteria constitute a specific group of commensal bacteria which inhabit the gastrointestinal tract of humans and other mammals. Bifidobacterium breve UCC2003 has previously been shown to utilise several plant-derived carbohydrates that include cellodextrins, starch and galactan. In the curren...

ProteomicsOptimization of O-GIG for O-glycopeptide Characterization with Sialic Acid Linkage Determination-Fig6
O-glycoprotein analysis has been historically challenging due, in part, to a dearth of available enzymes active in release of O-glycans. Moreover, chemical releasing methods, such as β-elimination/Michael addition are not specific to O-glycan release and can also eliminate phosphoryl substitutions....
