Crystal structure of the Large Type III Glutamine Synthetase from Bacteroides Fragilis

, 2010
Glutamine synthetases are one of the most ancient functioning enzymes in existence and these large oligomeric complexes are found in all extant forms of life where they play a critical role in nitrogen metabolism.

Gemella morbillorum Promotes Colorectal Carcinogenesis: LPBDCP‐Mediated Invasion Activates Ras Signaling and Destabilizes p53

Advanced Science, Volume 13, Issue 34, 19 June 2026.
ABSTRACT Gut microbiota dysbiosis promotes colorectal cancer (CRC) tumorigenesis. A global fecal metagenomic analysis identified Gemella morbillorum as a key contributor to the CRC‐associated microbiota. Fluorescence in situ hybridization revealed that Gemella morbillorum is enriched in CRC tumor tissues compared to adjacent normal tissues.

Continuous Alterations in the Gut Microbial Landscape Associated With Suicidal Ideation in First‐Episode Drug‐naïve Major Depressive Disorder

CNS Neuroscience &Therapeutics, Volume 32, Issue 6, June 2026.
We define a gut‐microbiota gradient linked to increasing depression severity and suicidal ideation, highlighting severity‐tracking taxa and pathways, particularly Bacteroides stercoris and the bacterial secretion‐system pathway, as potential microbial markers for suicide risk in MDD.
