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.

Roles of PknB and CslA in Cell Wall Morphogenesis of Streptomyces

Molecular Microbiology, Volume 126, Issue 2, Page 161-172, August 2026.
Streptomyces grow by extending hyphal tips, a process regulated by polarisome complexes anchored by DivIVA. Using a genetic screen based on toxic DivIVA overproduction, we identified the kinase PknB as a key regulator of cell envelope construction.

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.

GpaR Drives Type III Secretion and Virulence Through Direct Activation of the HrpG‐HrpX Cascade in Xanthomonas oryzae pv. oryzicola

Molecular Plant Pathology, Volume 27, Issue 8, August 2026.
GpaR directly activates hrpG and hrpX, triggering the HrpG–HrpX cascade to promote virulence in rice and induce the hypersensitive response in nonhost plants, revealing a key upstream regulator of type III secretion and pathogenicity in Xanthomonas oryzae pv. oryzicola. ABSTRACT Xanthomonas oryzae pv. oryzicola (Xoc), the causal agent of bacterial leaf

Complex Regulation of RETINOBLASTOMA‐RELATED's Interactions With E2Fs via Phosphorylation

Plant, Cell &Environment, Volume 49, Issue 8, Page 4717-4733, August 2026.
ABSTRACT Arabidopsis RETINOBLASTOMA‐RELATED (RBR) regulates cell proliferation by interacting with E2F transcription factors and DIMERISATION PARTNER, RB‐LIKE, E2F AND MULTI‐VULVAL CLASS B COMPLEX (DREAM) components. Although CDK‐CYCD phosphorylation is believed to affect RBR's E2F‐binding capacity, the precise phosphorylation events inhibiting RBR's ...
