Biofluid Biomarkers of Cognitive Functioning in Bipolar Disorder: A Systematic Review by the Targeting Cognition and Older‐Age Bipolar Disorder ISBD Task Forces

Bipolar Disorders, Volume 28, Issue 5, August 2026.
ABSTRACT Background Cognitive impairment is common in bipolar disorder (BD), but the underlying pathophysiology remains unclear. This systematic review aimed to (1) summarize all literature describing relationships of biofluid biomarkers and cognition in BD and (2) identify which biofluid biomarkers correlate most consistently with cognition in BD ...

The regulatory roles of liver and kidney in cobalamin (vitamin-B(12)) metabolism in the rat: the uptake and intracellular binding of cobalamin and the activity of the cobalamin-dependent enzymes in response to varying cobalamin supply [PDF]

, 1984
To examine possible regulatory roles of liver and kidney in cobalamin metabolism, specific activities of the two cobalamin-dependent enzymes, uptake in vivo of cyano [57Co]cobalamin [( 57Co]CNCbl) and the binding of [57Co]Cbl to intracellular proteins ...

Protein STM3547 From Salmonella typhimurium Is a Phosphofructose Kinase B‐Type Enzyme With Ribose Kinase Activity

Molecular Microbiology, Volume 126, Issue 2, Page 129-144, August 2026.
The metabolism of ribose starts with the phosphorylation of its 5′ hydroxyl group. Salmonella typhimurium has two kinases that perform this function, namely ribose rinase (RbsK) and deoxyribose kinase (DeoK). Here we report a new ribose kinase that we named RikA. The illustration was partially created in BioRender.

Chain‐Length Regulation by WzzE Is Necessary for, but Genetically Separable From, Cyclic Enterobacterial Common Antigen Synthesis

Molecular Microbiology, Volume 126, Issue 2, Page 190-207, August 2026.
Here, we demonstrate that polysaccharide chain length regulation plays a distinct role in enabling formation of a cyclic molecule important for the bacterial cell surface. However, this function is necessary, but not sufficient for the cyclic molecule's biosynthesis.

S‐Adenosyl‐d‐Methionine as a Non‐Physiological Substrate for a Wide Range of SAM‐Dependent Enzymes

ChemBioChem, Volume 27, Issue 14, 29 July 2026.
From methylation and cyclisation to radical chemistry, diverse enzyme classes utilise the non‐canonical cofactor d‐SAM. These findings reveal an unexpected tolerance of SAM‐dependent catalysis towards inversion of the methionine Cα stereocentre. The ability of SAM‐dependent enzymes to accept S‐adenosyl‐d‐methionine [d‐SAM, (SS,RCα)‐SAM] instead of the ...
